Abstract
Using results from our analysis of rotational and infrared spectra of $\nu_2,\; \nu_3,\; \nu_5,$ and $\nu_6$ we have fit the hot bands in the $\nu_6$ region near 774 cm$^{-1}$ originating in $\nu_2,$ $\nu_3,$ and $\nu_5$ as well as the $2\nu_6$ overtone band. Although the $2\nu_6$ state is perturbed by the nearby and as yet unassigned $\nu_2+\nu_3$ and $\nu_2+\nu_5$ states, a set of effective parameters was derived which adequately describes the $2\nu_6$ spectrum as well as the $2\nu_6-\nu_6$ hot band. These results improve the description of the $\nu_6$ spectrum, particularly in the Q-branch region. The molecular parameters will be presented and examples of spectra will be shown.
