Abstract
The far infrared spectra of a number of aliphatic amines have been recorded as dilute solutions in cyclohexane. A characteristic band with center at 225 ± 10 cm−1 is present in the spectra of aliphatic primary amines with a primary α-carbon atom. On the basis of the deuterium shift this band is assigned to the amino torsion. The effects of branching at the α-carbon, coupling of methyl and amino torsions, and intramolecular association on the frequencies of NH2 torsions are discussed.Keywords
