    Notes: The FeH2 radical has been detected in the gas phase through the observation of transitions in the fundamental band of the antisymmetric stretching vibration ν3. The molecule was generated in an electrical discharge through a mixture of hydrogen and iron pentacarbonyl in helium and the signals were recorded by the technique of laser magnetic resonance. It is established that the molecule is linear in its ground state and that this state is 5Δ in character; theoretical calculations suggest that it has gerade symmetry. The vibrational band origin is determined to be 1674.7196(4) cm−1 and the rotational constant for the (0,0,0) level is 3.01328(3) cm−1. This latter value corresponds to an r0 Fe–H bond length of 0.1665 nm. © 1996 American Institute of Physics.

    Notes: By use of a free-jet expansion which incorporates a heated nozzle, we have recorded the laser excitation spectrum of the 460 nm band system of NiCl2 at rotational resolution. The rotational temperature in these recordings was about 12 K. Several bands have been recorded and analyzed for three isotopomers, 58Ni35Cl2, 60Ni35Cl2, and 58Ni35Cl37Cl in natural abundance. Spin components with Ω values of 0 and 1 have been identified in both the upper and lower states of the transition. Accurate values for all three vibrational intervals ν1, ν2, and ν3 have been determined for nickel dichloride in the upper state and for the bending wave number ν2 in the lower state. The results show that the molecule is linear in both states involved in the transition and that the lower (ground) state is 3Σ−g in character. Evidence is presented from the nickel isotope shifts to show that the transition is vibronically induced through the bending vibration and that the upper state is vibronically 3Πu in character; it probably derives from an electronic 3Δg state. The zero-point averaged bond lengths are determined for both states as r0′=0.209 435(13) nm and r0″=0.205 317(14) nm. The fine structure parameters for the X˜ 3Σ−g state are interpreted in terms of low lying 1Σ+g and 3Πg states, which are shown to lie a few thousand reciprocal centimeters above the ground state. © 1996 American Institute of Physics.

    Notes: The molecular species In2O has been identified in the gas phase as a product of the high temperature reaction between water and indium (850 °C) or between indium trioxide (In2O3) and indium (950 °C) by the observation of an electronic transition in the near-ultraviolet. The spectra are simplified by supersonic cooling of the sample in a free jet expansion after it is formed. The vibrational structure shows that the molecule has a very similar geometry in the two states involved while the 18O/16O isotope shift suggests that the molecule is only slightly nonlinear in the excited electronic state. Rotational structure can be resolved at high resolution and shows an intensity alternation; the molecule thus has a symmetric In–O–In arrangement. © 1997 American Institute of Physics.

    Notes: The technique of laser excitation spectroscopy at Doppler resolution has been used to record bands in the electronic spectrum of FeH around 532 nm. A number of lines were also recorded at sub-Doppler resolution using intermodulated fluorescence spectroscopy. Dispersed fluorescence studies were used extensively to aid the assignment of a total of 153 lines in this region of the spectrum to either the (0,0) or the (0,1) band of the e 6Π–a 6Δ transition. All the assignments from the excitation spectrum obey the selection rule ΔΩ=−1, giving subbands which involve the lowest three spin components in each state; transitions with ΔΩ=0 were seen only in dispersed fluorescence. Term values have been determined for the three components in both the ground vibrational level of the e 6Π electronic state and the first excited vibrational level of the a 6Δ electronic state (those for the v=0 level of the a 6Δ state have been determined previously). This study provides the first characterization of the spin components and the rotational levels of the e 6Π state of FeH. This state is heavily perturbed and exhibits pronounced lambda-type doubling, making it very difficult to model the energy levels using an effective Hamiltonian approach. © 1997 American Institute of Physics.

    Notes: The fine-structure transition 2Π1/2←2Π3/2 of the free radical FO has been detected by far-infrared laser magnetic resonance. All the observed transitions are magnetic dipole in character. The spin–orbit constant A0 has been determined experimentally; its value of −196.108 686(50) cm−1 is consistent with previous estimates. The analysis of a set of 290 transitions leads to the determination of a number of molecular parameters including rotational, centrifugal distortion, spin–orbit, lambda-doubling, magnetic hyperfine, and Zeeman terms. All four magnetic hyperfine structure constants a, bF, c, d for the 19F nucleus have been determined and are discussed in terms of the expectation values of the appropriate operators over the electronic wave function. © 1999 American Institute of Physics.

    Notes: An investigation of the electronic spectrum of FeH at ∼630 nm using dispersed and undispersed laser induced fluorescence techniques is reported. Eighty lines have been assigned to the (0,0) vibrational band of the e 6Π–c 6Σ+ transition. The transitions can be arranged in three subbands with all six spin components of the c 6Σ+ state accessed. This has allowed the c 6Σ+ state to be fully characterized and provides parity assignments of individual rotational levels for the first time. The energy levels of the c 6Σ+ state conform approximately to a Hund's case (a′) coupling scheme with significant Ω-type doubling (1–10 cm−1). An attempt has been made to simulate the levels using an effective Hamiltonian. Although the simulation failed to reproduce the results to within experimental uncertainty (∼0.007 cm−1), the residuals are sufficiently small to confirm the correctness of the assignments. © 1998 American Institute of Physics.

    Notes: Examines the complex issues involved in developing a school leadership programme in the Republic of Georgia. Intends to serve as an inventory for other newly independent states seeking to transform their educational systems. By discussing eight conditions that result in differences in the practice of education among countries, frames a perspective for additional research. Chronicles the historical context of Georgian life and culture and includes a discussion of education reform efforts, philosophy and the current education system. Interwoven in the historical developments and traditions and their interaction with current economic, social and political realities, presents ten major issues that must be resolved prior to the development of an effective school leadership programme.

    Notes: The potential and the problems of multicultural theatre have frequently been described and debated in this as in other theatre journals, but discussions of its value and viability have generally been in ethical terms – over how far it is possible for the West to ‘import’ or otherwise employ the theatrical traditions of other cultures without resort to an imperialist appropriation of what is found ‘consumable’, to the detriment of the culture thus despoiled. While not ignoring the moral arguments, John Russell Brown here deals also with the practical issues – notably, how far different kinds of theatre depend on being ‘site-specific’ not only in terms of the performers involved, but also in terms of audiences and their responses. He argues that, paradoxically, truly intercultural theatre is more often to be found where western influences from Hollywood films or pop music have become part of the lived experience of eastern cultures, or in western communities where (for example) British and West Indian or ‘Anglo’ and Latino-American traditions have become intertwined. He suggests that rather than trying to embrace the substance of ‘other’ traditions, western theatre might better benefit by exploring the conventions that modulate the relationship between actors and audience, or the approach of the actor to different kinds of ‘text’. He concludes: ‘By using overseas research to develop its own inheritance, a theatre might discover what it alone needs to create and encourage a more active and imaginative response from its local audience.’ A widely published writer on drama and theatre, John Russell Brown was first Head of the University of Birmingham's Department of Drama and Theatre Arts, and was subsequently an Associate Director at the National Theatre in London. Currently he is visiting Professor at Columbia University, New York.
