Abstract
Integrated absorption intensities of OH stretching bands, from the fundamental through the third overtone, have been measured for vapor-phase methanol, ethanol, isopropanol, n-propanol, 1,1,1-trifluoroethanol, tertiary butanol, and nitric acid. Several trends apparent in these data will be discussed. For example, the fundamental OH band intensities are much more consistent than those in CH containing $molecules^{ab}$. Furthermore, the overtone intensities are even more consistent, and appear to be essentially indential for the second overtone, at least among the compounds examined thus far. Trends in the intensities as a function of excitation level will be modeled, and the dipole moment functions which result from this procedure will be compared to those obtained from molecular orbital calculations.
