THE INFRARED SPECTRA OF CH₄, CH₃D, CH₂D₂, CD₃H, AND CD₄

Abstract

The infrared spectra of all the deuterated methanes of high isotopic purity have been obtained with prism resolution and 27 of the 29 fundamentals were observed. The frequencies observed have been compared with the previous grating and prism data and 'best' values of the fundamentals have been suggested. The present data are considered to give more reliable frequencies for most of the fundamentals of CH 3 D, CH 2 D 2 , and CD 3 H than were previously available.
