Laser Excited Raman Spectrum of an Oriented Crystal of Trans Bisdimethylsulphide Dibromo Platinum (II)

Abstract

THE investigation of the Raman spectra of single crystals is a well established technique, but the use of plane polarized uni-directional exciting radiation is difficult and has been applied only to “ideal” cases. The difficulty arises from the inherently low intensity of discharge lamp sources when they are operated at a pressure sufficiently low for the lines in their spectrum to be narrow and therefore useful. Recently, the laser has been evolved and provides a far more satisfactory source for this work.
