Vibrational intensities in methane

Ian Mills
- 01 Apr 1958 - 
TL;DR: In this paper, the absorption intensities of the two infra-red active vibrations in methane have been obtained from a perturbation calculation on the equilibrium wave functions derived in the preceding paper.
Journal ArticleDOI

Some theoretical considerations about vibrational band intensities

TL;DR: In this article, it is shown that the transverse moment of a bond appears sometimes to contribute almost as much as any of the other factors to the total change of total molecular dipole moment.

The Infrared Dispersion of Acetylene and the Dipole Moment of the C-H Bond

TL;DR: In this paper, the contributions of the molecular vibrations to the index of refraction of acetylene have been determined and interpreted in terms of effective charges on the constituent atoms, and a comparison of these results with previous work indicates a possible regularity in the C-H bond moment in going from methane to ethylene to acetylene, although the regularity may only apparent.

Are Molecular Orbitals Delocalized

TL;DR: In contrast to statements in a recent article in this Journal, the bonding electrons in methane can be properly described in terms of localized electrons, and photoelectron spectroscopy does not indicate otherwise.

Electrically Induced Perturbations of Halogen Nuclear Quadrupole Interactions in Polycrystalline Compounds. II. Microscopic Theory

TL;DR: In this paper, the physical origins of electrically induced perturbations of quadrupole couplings in molecular solids are considered, and it is concluded that polarizations of bonding electrons near the resonant nuclei are of dominant importance in determining the magnitudes of the electric induced shifts.
