The Raman spectra of some organic halogen compounds

The Raman spectra of organic compounds have recently been the subject of investigation in many laboratories. As yet, however, only a few organic halogen compounds have received attention. It was considered that a detailed investigation of several compounds of this class would throw light on fundamental questions concerning the Raman effect. Some 17 halogen derivatives of the aliphatic and aromatic hydrocarbons were accordingly investigated by the authors and the results are described in this paper. The experimental arrangements are those recommended by R. W. Wood. The accompanying tables show the analysis of the Raman lines. Under the column ∆v are given the differences between the wave-numbers of Raman lines and the exciting lines of the mercury spectrum λ. Å. U. 3650·1, 3654·8, 3663·3, 4046·6, 4077·8, 4339·2, 4347·5, 4358·3, 5460·7, 5769·5, and 5790·5 repre­sented by the letters a, b, c, d, e, f, g, h, k, l and m respectively. Those Raman lines which happen to coincide with the incident lines of the mercury spectrum are not included in the tables.
