✦ Synopsis

The Raman spectra of (CH,),AsCl, (CH,)2AsBr, (CH,),AsI and of CH,AsCI,, CH,AsBr, and CH,AsI, are reported. For (CH,),AsCI and CH,AsCI, depolarization factor measurements were made. A description of these methods is briefly outlined. The results of this spertral investigation indicate that all these compounds may be described by a structure of symmetry Clh = C,.

The results are interpreted in terms of bond contraction of the As-Cl bond by substituting C1 for CH, in (CH,),AsCI, CH,AsCl, and AsC1,. These contractions are in full agreement with the previous theory of Skinner and Sutton. (l) H. A. SKINNER and I,. E. SUTTON, Trans. Faruday SOC., 40, 164-84 19(44).
