Band Series in Infra-Red Absorption Spectra of Organic Compounds. II

Abstract

The absorption bands of secondary intensity occurring, in addition to the more pronounced members of the previously described C-H series, in the short wave-length infra-red spectra of methyl iodide, methylene chloride, methylene bromide, methylene iodide, chloroform and bromoform are accounted for on the basis of linear C-Cl, C-Br, and C-I series starting at 16.8\ensuremath{\mu}, 17.2\ensuremath{\mu} and 17.5\ensuremath{\mu} respectively; and on the basis of simple additive combinations between these frequencies and those of the C-H series.
