✦ Synopsis

The polarized Raman spectrum of solutions, and the infra-red spectra of solutions and isooriented films in polarized radiation have been measured for 1,2-dichloro-and for the previously unknown l-chloro-2-bromo-and 1,2 dibromocyclobuten-3,4-dione.

A normal coordinate analysis has been carried out with the aims of obtaining an acceptably low dispersion force field and a good agreement with the experimental frequencies.
