6 REGION AND THE 2
6 OVERTONE.

Using results from our analysis of rotational and infrared spectra of
2,
3,
5, and
6 we have fit the hot bands in the
6 region near 774 cm-1 originating in
2,
3, and
5 as well as the 2
6 overtone band. Although the 2
6 state is perturbed by the nearby and as yet unassigned
2+
3 and
2+
5 states, a set of effective parameters was derived which adequately describes the 2
6 spectrum as well as the 2
6-
6 hot band. These results improve the description of the
6 spectrum, particularly in the Q-branch region. The molecular parameters will be presented and examples of spectra will be shown.
