Abstract
A preliminary account is given of a comparative study of infrared spectra of simple amines and their chlorohydrates. Primary, secondary, and tertiary amines and their respective ions are studied,-- aliphatic, aromatic and aza-compounds -- and a general view on these spectra is sought. The effect of lonization on the amino-groups is discussed on the basis of the NH stretching and bending bands. Other bands in the spectra give information on modifications in the structure of the hydrocarbon part of these molecules following ionization. All the amines and ions were examined in various media: liquid or solid, aqueous solutions if possible, and solution of the hydrochlorides in their own amines or other amines when the latter are liquids. Relations between spectra taken in these media change in a significant manner for different types of compounds. The results are compared with known ultraviolet data.
