Abstract:A full normal coordinate analysis (NCA) has been carried out on monomethylhydrazine and N-deuterated monomethylhydrazine. The C symmetry of the methyl group is lost; nevertheless the concept of specific methyl group modes is still valuable. The NN stretching mode is relatively pure enabling it to be used as a criteria of coordination. An NCA has also been carried out for the bidentate nickel complex NiCl2(NH2NHCH3)2. Interesting effects are observed for the wagging and twisting modes of the NH2 group on coordination.
