Abstract

At the last two ISMS meetings we have reported on our IR studies of various D and $^{13}$C substituted isotopologues of propane conducted at the Canadian Light Source synchrotron (2-$^{13}$C, 1-$^{13}$C, 2,2-D$_{2}$, 2-D$_{1}$). This year we are reporting on the study of the \nub{9} B-type band of 1-D$_{1}$-Propane. There are only two reports of the IR spectra of this molecule both published in 1949. Neither of these studies could reach the far-IR where this band occurs.
We will show the complete high resolution survey of all regions from 4000 to below 300 \wn. This will help to confirm some of the earlier assignments for this molecule.
We hope to report the first modern experimental determination of the ground state constants since the 1960 MW study of Lide. This new work now includes the centrifugal distortion terms for the ground state as well as constants for the \nub{9} state.
