Raman Effect in Gases and Liquids

Abstract

IN a note recently communicated to NATURE it was pointed out that the Raman effect in triatomic molecules having a linear model could be explained on the assumption of a fundamental mode of vibration along the line joining the three nuclei of the molecules. Such vibrations take place along the direction of propagation of the radiation and behave as optically inactive ones and are not manifested in the near infra-red bands. The case of carbon dioxide was discussed on this basis.
