Abstract
Deuteration, concentration, and temperature studies are employed to establish the 1.99- mu m band of primary butylamines to be free N- H absorption and the 2.02- mu m band to be hydrogen-bonded N-- II absorption. The effect of amine structure on absorptivity of these bands is noted and correlation of Taft + sigma * values to the 2.02 mu m absorbance observed. The absorbance at 2.02 mu m is also correlated to solvent-solute hydrogen bonding. The interrelationships of concentration, amine structure, and solvent-solute hydrogen bonding as to their effects on the 1,99- aud 2.02- mu m combination bands of primary butylamines are discussed.
