THE INFRARED ABSORPTION SPECTRA OF DEUTERATED ESTERS: III. METHYL LAURATE

Abstract

The infrared absorption spectrum of methyl laurate in carbon tetrachloride and carbon disulphide solutions has been compared with the spectra of seven derivatives deuterated in the ω-methyl group, the α-methylene groups, the carbomethoxy group, and in binary and ternary combinations of these positions. The spectra of n-dodecanes deuterated in the terminal methyl groups and of methyl laurates chlorinated in the ω-methyl and α-methylene groups have also been measured.From an analysis of these spectra, all the bands and inflections between 3100 and 700 cm⁻¹ in the spectrum of methyl laurate can be assigned to localized group vibrations. The spectra of some related acid chlorides, alcohols, and bromides are also briefly noted.
