New Tests of Models in Chemical Binding — Extra-Mechanical Effects and Molecular Properties

  • J. F. Ogilvie


We examine the validity of two models according to which we derive information about structural, dynamic, electric and magnetic properties of small molecules from analysis of frequency data of vibration-rotational spectra in absorption or emission. One model is the atomic approximation, according to which we associate with a particular atomic centre (atomic nucleus) electrons of number approximately equal to the protonic number of the nucleus; by this means we derive structural and dynamic information. Another model of the diatomic molecule is a rotating electric dipole, according to which parameters associated with extra-mechanical (adiabatic and nonadiabatic) effects yield information about electric and magnetic properties, namely the permanent electric dipolar moment and the rotational g factor. Spectral data of LiH and GeS are employed as tests of these models, on the basis of which evaluation of these properties proves practicable for other small molecules, for which illustrations are presented.
