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.
