Abstract
Infrared and Raman spectra of thiazole have been reinvestigated with new assignments of overtone and combination bands being proposed. Infrared spectra in the solid phase and in different solutions for 2-aminothiazole and 2-amino-[2H2]-thiazole, as well as Raman spectrum of microcrystalline powder for 2-aminothiazole were also studied and a general assignment for all the observed bands have been proposed. The present assignment satisfies the isotopic product rule for i.r. fundamentals. On this basis thermodynamic functions have been computed.
