DETERMINATION OF RATES OF CHANGE OF POLARIZABILITY FROM RAMAN AND RAYLEIGH INTENSITIES

Abstract

Mean values of the rate of change of polarizability with respect to internuclear distance were determined for several molecules from the ratio of Raman and Ray-leigh intensities in the gas. The values obtained are: hydrogen, 1.2 × 10−16 cm.2; deuterium, 1.1; hydrogen chloride, 1.0; hydrogen bromide, 1.2; nitrogen, 1.6; oxygen, 1.4; carbon dioxide (ν1 vibration), 4.2; methane (ν1 vibration), 4.1. It is noteworthy that the values for the partially ionic molecules, hydrogen chloride and hydrogen bromide, are nearly the same as for hydrogen and deuterium.
