Polarization of the Raman Line of the Totally Symmetric Vibration of Stannic Chloride

IT is well known that the depolarization factors of the Raman lines produced by the totally symmetric vibrations of the XCl₄ molecules of the tetrahedral type are not zero¹. Recently in this laboratory, it has been shown that the depolarization factors are smaller than the results given by many investigators; but they definitely are not zero².
