    Notes: Abstract The representation of atomic p orbitals in terms of tetrahedral Gaussian lobe functions is shown to be a viable alternative to more conventional representations in terms of cartesian Gaussians or octahedral lobe functions. Fairly accurate SCF calculations for the methane and ethane molecules show that the flexibility of the tetrahedral representation can be used to introduce a degree of polarization into the atomic basis in a molecular environment. Combined with the use of molecular bond functions, this flexibility provides an economical description of polarization effects in molecules.

    Cytological analysis of complex-heterozygotes in populations ofOenothera grandiflora (Onagraceae) in Alabama (1993)

    Topics: Biology
    Notes: Abstract Genetic analysis of unusual complex-heterozygous genotypes in populations ofO. grandiflora from Alabama (USA) has shown that these strains are composed of a typicalgrandiflora (B) complex and an altered B complex (designated as BA) which probably contains genetic elements derived from an A genotype such as the beta complex ofO. biennis group 1. Analysis of the meiotic configurations of artificial hybrids between the new strains and a series of complexes of known segmental arrangement allowed determination of the arrangements of the unknown complexes. These data are evidence for origin of the altered B complexes.

    Notes: Coupled Hartree-Fock theory is used to compute and map the current density induced in planar hydrocarbons by an external magnetic field. Results of useful accuracy can be obtained with modest (6-31G**) basis sets by employing a continuous gauge transformation. Maps are presented and discussed for benzene, naphthalene, anthracene, tetracene, pentacene, heptacene, and biphenylene. © 1996 John Wiley & Sons, Inc.
