 Title: INFRARED ABSORPTION SPECTRUM OF $CH_{4}$ AT 9050 $CM^{-1}$ Creators: Margolis, J. S.; Fox, K. Issue Date: 1968 Publisher: Ohio State University Abstract: A high resolution infrared absorption spectrum is presented for the region of the R branch of the second overtone of the triply degenerate fundamental $\nu_{3}$ of $CH_{4}$. Comparisons are made between the tetrahedral fine structure splittings in this spectrum, in the spectra of $\nu_{3}$ and $2\nu_{3}$ of $CH_{4}$ and $2\nu_{3}$ of $CD_{4}$, and in the theoretical dominant $approximation.^{1}$ Description: Supported by NASA Contract NAS7-100. Kenneth Fox is NRC-NASA Resident Research Associate, on leave from The University of Tennessee. $^{1}$ K. T. Hecht, J. Mol. Spectry, 5, 355 (1960).
