Refractive indices and dispersions of volatile compounds of fluorine and boron

Abstract

1. The refractive indices and dispersions of carbon tetrafluoride, nitrogen trifluoride, fluoroform, nitrogen-carbon compound of fluorine (CF3N)2, boron hexahydride and nitrogenous boron hydride B3N3H6, have been measured at the ordinary temperature using a Zeiss Interferometer of the Rayleigh type. 2. The compressibilities of the gases mentioned have been determined by studying the variation of refractive index with pressure. 3. The atomic polarisations of these molecules have been calculated from the dielectric and optical polarisations. It has been found that the fluorine compounds and the complex compound of boron B3N3H6, have appreciable values of atomic polarisations.
