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 possible conformations of the mobile compounds. Equilibrium constants derived from the shifts of the contributing conformations agree with results of low temperature ^13^C NMR spectroscopy.

## 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

Proton NMR data for a number of l-.IZ-4-Y-3,5-dimethylbenzenc?s and l-X-2-Y-4-Z-3,5-dimethylbenzenc?s are presented. The proton chemical shifts of the methyl groups at positions 3 and 5 are mainly affected by the ring current effect of the snbstituents. Thii conclusion was strongly supported by the
