Electron Density Distribution around Hydrogen Atoms in Linear Molecules

Electron densities around H atoms in linear HX molecules (X--H, F, C1, OLi, ONa, CN, CP, Bell, Li and Na) were calculated in two directions relating to the major and minor radii. A Hartree-Fock level of theory with the 6-311G(2d, p) or MC-311G(2d, p) basis sets was applied. Van der Waals radii of the H atoms in the isolated molecules were estimated at the position where the electron density is 0-005 a.u. (0.0337 e A-3). The anisotropy of both the electron density distributions and the van der Waals radii of the H atoms was clearly confirmed in all the molecules. The radii and the degree of anisotropy are linearly related to both the Mulliken atomic charges on the H atom and the electronegativity of the
