Abstract
The salient features of the vibration of larger molecules is localization. One of the consequences is the fact that it is possible to write the effective potential energy for modes localized in a group as \[ V_{e}=V_{g}\;(r_{g})-V_{gr}(r_{g})-V^{\prime}_{gr}(r_{g}, r_{r}) \] The effective selection rules, degeneracy of the frequencies, etc., depend upon the relative magnitudes of these terms. This point of view is applied to the Raman and infrared (prism and small grating) spectra of the methyl derivatives of tin tetrachloride. Some intensity as well as frequency measurements have been made. The localized mode method was used to make normal coordinate calculations.
