    Notes: J=2→3, 3→4, 4→5, and 5→6 transitions in the oblate symmetric top molecule cobalt tricarbonyl nitrosyl were measured using a Flygare–Balle type pulsed beam microwave spectrometer. K=0 and K=3 transitions were observed for J=3→4 and 4→5. Hyperfine structure due to 59Co and 14N nuclear quadrupole coupling interactions was well resolved. The measured quadrupole coupling strengths are eQqcc (59Co)=35.14(30) MHz and eQqcc (14N)=−1.59(10). Measured rotation and distortion constants are B0=1042.1590(4) MHz and Dj =0.17(8) kHz. The measured B value is 4% smaller than the B value calculated from electron diffraction data. Spin–rotation and a quadrupole distortion term were also obtained for 59Co.

    Notes: High resolution rotational spectra for 21 isotopic species of the hydrogen cyanide–mercury complex have been measured in the 7–15 GHz region using a Balle/Flygare pulsed Fourier transform microwave spectrometer. Rotational constants and 14N nuclear quadrupole coupling constants are (in MHz), for HC14N202Hg: B0=1265.6627(7), DJ=0.020 669(14), χN=−0.695(12), and for DC14N202Hg: B0=1201.8338(16), DJ=0.021 213(45), and χN=−0.748(19). The 201Hg nuclear quadrupole coupling constants are, for HC15N201Hg: −5.97(13) MHz, and for DC15N201Hg: −6.03(24) MHz. The atomic arrangement is HCN...Hg with a zero-point vibrationally averaged center-of-mass separation of 4.05 A(ring) for the most abundant HC14N202Hg species. The equilibrium structure was not determined. HCNHg does not exhibit the extreme centrifugal distortion and isotopic sensitivity effects seen in ArHCN [K. R. Leopold, G. T. Fraser, F. J. Lin, D. D. Nelson, Jr., and W. Klemperer, J. Chem. Phys. 81, 4922 (1984)].

    Notes: Abstract Objective: to evaluate the psychometric performance of a new human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS)-targeted quality of life (QoL) instrument in asymptomatic HIV-seropositive individuals. Methods: 201 urban and rural, HIV-seropositive subjects were recruited to complete a 76-item pilot QoL measure developed using content provided in group process by seropositive individuals. Questionnaire responses from the full sample (n=201) were used to identify dimensions and to reduce the number of items to 42. The responses to the retained items were then analysed for the asymptomatic subsample (n=106). Results: 9 multi-item dimensions were identified: overall function (OF), sexual function (SF), disclosure worries (DW), health worries (HW), financial worries (FW), HIV mastery (HM), life satisfaction (LS), medication concerns (MC) and provider trust (PT). The responses by asymptomatic subjects (74% male, 64% non-White and 63% homosexual/bisexual) revealed no substantial floor or ceiling effects, except for the PT dimension (where 44% were found to have scored the highest score). The internal consistency coefficients (Cronbach's alphas) were between 0.80 and 0.89 for six dimensions. The coefficients were lower for the SF (0.52), HM (0.67) and MC (0.48) dimensions. Construct validity assessments, using self-reported HIV disease-severity and sociodemographic variables, revealed some significant relationships (p≤0.05) for all dimensions except SF, MC and PT. Conclusions: the results suggested that five dimensions (OF, DW, HW, FW and LS) from the new instrument have good psychometric properties for asymptomatic HIV-seropositive individuals. These dimensions may be useful in the study of asymptomatic, seropositive individuals' QoL. Four dimensions (SF, HM, MC and PS) require additional refinement for this subpopulation.
