The absortion electronic spectrum of pentachlorobenzene, perchlorobenzene, 2,3,4,5,6-pentachlorotoluene, 2,3,4,5,6-pentachloro-1-chloromethylbenzene, 2,3,4,5,6-pentachloro-1-dichloromethylbenzene, 2,3,4,5-tetrachloro-1-trichloromethylbenzene, 2,3,5,6-tetrachloro-1-trichloromethylbenzene, perchlorotoluene, perchloroethylbenzene, 1,4-bistrichloromethylbenzene, 2,5-dichloro-1,4-bistrichloromethylbenzene, perchloro-p-xylene, and pentamethyltrichloromethylbenzene, from 200 millimicrons to the visible region, are reported and discussed. Those compounds having trichloromethyl groups flanked by two ortho chlorine atoms show abnormal spectra, consisting chiefly in great bathochromic shifts of some of their bands from their expected places, which is accounted for in terms of steric strain and molecular distortion.
