## Abstract Several sulfanilamide‐type compounds in their solid state have been investigated by the ^14^N nuclear quadrupole resonance (NQR) technique. The electron distributions at the sites of the nitrogen atoms, calculated by the Townes and Dailey theory, indicate a significant correlation betwe

The microwave spectrum of m-tolunitrile (3-methylbenzonitrile, m-C 6 H 4 CH 3 CN) has been investigated in the frequency range from 1 to 4 and 8 to 26.5 GHz. The spectra in the two lowest states of internal methyl rotation (m ϭ 0, Ϯ1) were recorded by means of pulsed molecular beam Fourier transform

## Abstract Measurements are reported of NH exchange rates of urea, thiourea, acetamide and thioacetamide, using line‐shape analysis with natural‐abundance ^15^N NMR spectra. Base‐catalyzed NH‐proton exchange of thiourea is 30–40 times faster than for urea, while the corresponding acid‐catalyzed ex
