The formation of a charge transfer complex between pyridine and halogens or mixed halogens(1,2)brings about perturbations in the infrared spectra of the pyridine molecule and many halogen complexes show two bands in the low frequency range, which can be attributed to thevX-XandvN…Ystretching vibrations.(3–5). However, by comparison, very little has been reported on the Raman spectra of such complexes. Klaboe(6)studied thevBr-BrRaman frequency of some bromine complexes and more recently the Raman spectra of pyridine complexed with Ni (CN)4(7)and TiCl4(8)have been reported. In this work, the Raman spectrum of the 3-Br pyridine-bromine charge transfer complex is investigated.
