Infrared and Raman spectra of solid cyclopropane, cyclopropane-d 6 , and the mutual solid solutions of these isotopic molecules are reinvestigated in the regions of internal vibrational modes. Several modifications of previously reported fundamental assignments are presented. Frequencies of components of internal fundamentals resulting from site and correlation field splittings are calculated from published atom—atom potential functions. Calculated splittings are in general found to be smaller than observed splittings, with correlation field usually contributing more than site splittings to total splittings, according to the calculations. |
