✦ Synopsis

Although there exists a large amount of data regarding the barrier to rotation about carbon-nitrogen bonds possessing greater than single-bond order, 1 relatively little information is available concerning rotation about legitimate carbon-nitrogen single bonds.

Microwave spectroscopy has revealed rotational barriers in CH3NH2 (AH? = 2.0 kcal/mole)2, (CH3)3N (AH+ = 4.4 kcal/mole)2, and CH3N02 (AH+ = .006 kcal/mole)2 while nmr spectroscopy gave the rate of t-butyl
