Abstract
We have investigated in great detail the infrared and Raman activity of . From experimental spectra collected at low temperature, we have first identified all , , , and frequencies predicted by group-theory arguments. Second, comparing our experimental findings with theoretical predictions for the isoelectronic sequence P to to , we have discussed the relative strengths of Cd-P and Ge-P bonds compared with In-P and Ga-P, respectively.
