Vibrational Intensities. IV. Bond Moments in C2F6

Abstract
The intensities of four of the infrared‐active fundamentals of C2F6 have been determined and interpreted in terms of the bond‐moment hypothesis. The bond‐moment parameters are overdetermined so that an internal check is provided. This check, supplemented by comparison with data on related molecules, shows that the bond‐moment picture is a useful approximation but that it is not quantitatively reliable.
