Abstract
The 14N nuclear quadrupole resonance spectra at 77°K of several hydrazines are reported and analyzed in the framework of a semiempirical theory extended to cover cases of large asymmetry parameters. The atomic‐orbital occupation numbers obtained by this analysis are linked with the hydrogen‐bonding configuration in the solid state. The results obtained indicate that the hydrogen bonding ability of the amino nitrogen exceeds that of the substituted nitrogen atom and decreases in the order: hydrazine>alkyl hydrazines>N‐amino heterocycles>aryl hydrazines.Keywords
