ABSOLUTE INTENSITIES OF THE $\nu_{2}$ AND $2\nu_{6}$ BANDS OF $CH_{3}D$

Abstract

High resolution $(\sim 0.006$ $cm^{-1})$ vibration-rotation absorption spectra of $^{12}CH_{3} D$ and $^{13}CH_{3}$ D have been recorded in the region between $1850\, cm^{-1}$ and $2500\, cm^{-1}$. The measurements were made with the two-meter optical path difference Michelson interferometer (which operates under vacuum conditions) at the Laboratoire d’Infrarouge. The intensities of individual lines were determined via measurements of their equivalent widths. Progress is repotted on the analysis of the observed ``local” and ``global” intensity perturbations.
