Intermolecular Coupling of Vibrations in Molecular Crystals. II. Intermolecular Forces in CH3Cl and CD3Cl

摘要: The effect of isotope substitution on band splittings caused by dipole coupling between molecules is examined. For methyl chloride and bromide, the results support contention that theory in its present form not sufficient to explain most bands.The atom‐atom interactions presented part I this series applied various possible potentials motions normal deuterated molecules. A repulsive potential acting hydrogen atoms neighboring accounts for several bands. Certain types seem ruled out these calculations, while others are left as factors shifts which occur when a gas condensed.
