Complete vibrational assignments have been obtained for tribromoethylene and cis dibromoethylene and thermodynamic functions calculated. Ten of the twelve fundamentals of trans dibromoethylene have been assigned and the approximate frequency of the missing pair evaluated by application of the frequency sum rule. The heat capacity of trans dibromoethylene has been calculated.

Infrared and Raman spectra of 2-mercaptoimidazole and 2-mercaptothiazole in solid state as well as i.r. spectra of 2-mercaptothiazole in HCCl3 and CS2 0.05M solutions have been investigated. A general assignment of all the observed bands is proposed for both fundamental vibrations and for overtone and combination bands. For 2-mercaptothiazole, the thiocarbonyl-form, intermolecularly hydrogen-bonded dimers in solid state, and unassociated molecules in dilute solutions of inert solvents have been established. Finally, based on this data, thermodynamic functions have been computed.
