Abstract
The Raman spectra of Si2H6(g) and of Si2Cl6(l) have been photographed. Polarization measurements of the stronger lines of Si2Cl6 have been made. From a consideration of the relations among the modes of vibration of similar molecules having different symmetry, the analysis of the observed lines is facilitated by a knowledge of the assignments of the fundamental frequencies of SiH4, HSiCl3 and BrSiCl3. A definite assignment is made for the three observed lines of Si2H6. A tentative assignment of the observed lines of Si2Cl6 is made and some evidence is presented for the existence of internal rotation in this molecule at room temperature.Keywords
