## 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

## Abstract The proton‐coupled nitrogen‐15 NMR spectra of hydrazinecarbothioamide and 4‐methylhydrazinecarbothioamide have been taken at the natural‐abundance level in neutral, basic and acidic solutions at 25°C. The NH proton‐exchange reactions of the hydrazino‐NH~2~ groups in both compounds were
## Abstract Nitrogen and carbon electron densities of the toluidines and xylidines have been recalculated by the INDO method; previously published errors have been corrected. Although the nitrogen‐15 chemical shifts of these compounds still display the earlier suggested correlation with σ and total
## Abstract ^15^N Chemical shifts of __cis__‐decahydroquinoline, __N__‐methyl‐__cis__‐decahydroquinoline, and of 19 methyl substituted NH‐ and NCH~3~‐__cis__‐decahydroquinolines are reported. Shift values of conformationally homogeneous compounds can be used to determine the chemical shifts of the
## Abstract The base‐catalyzed NH~2~ exchange reactions of acetamide and thioacetamide were studied by ^15^N nuclear magnetic resonance spectroscopy by the use of line‐shape analysis. The ^15^N NMR spectra of these primary amides at intermediate exchange rates were broad doublets, which indicated
