RAMAN SPECTRA OF SOLID CHLORINE AND BROMINE.

Abstract

Liberational lattice modes have been observed at 15K in solid Cl2 at 83, 100 and 118/cm and at 55, 74, 86 and 101/cm in solid Br2. Their intensities relative to one another can be qualitatively accounted for by the oriented gas model. The stretching frequencies of Cl2 and Br2 are shifted -13 and -20/cm respectively from their gas phase values (2) and show structure due to isotope splittings and intermolecular coupling. The spectra of the lattice modes, the Br2 stretching motion, and the Cl2 stretching motion indicate respectively strong, intermediate, and weak intermolecular coupling relative to the isotope splittings. Both lattice and internal frequencies indicate stronger intermolecular forces in solid Br2 than in solid Cl2. (Author)
