Abstract

The complete harmonic force field and optimized geometry of thiosemicarbazide have been calculated at the ab initio Hartree-Fock level using the 3-21G basis set. On the basis of this, the frequencies of $thiosemicarbazide-d_0$ and ${-d}_5$ and their $^{15}N$ isotopic molecules have been calculated. The calculated frequencies and their band assignments are utilized to critically examine our previous experimental assignments which were based on normal coordinate calculations. The theoretical IR and Raman intensities, together with qualitative experimental band intensities, are also presented.
