 Title: EXTENDED ASSIGNMENT OF $CH_{3}^{+}$: $v_{3}$ FUNDAMENTAL AND HOT BANDS Creators: Jagod, M.- F.; Gabrys, C. M.; Oka, T.; Rosslein, M. Issue Date: 1992 Abstract: We have completed a high sensitivity survey of our $CH_{4}$-$H_{2}$-He, liquid-nitrogen-cooled discharge from $3300 cm^{-1}$ down to $2900 cm^{-1}$. Many of the newly observed lines have been assigned to the $v_{3}$ fundamental band of $CH_{3}^{+}$, substantially extending our previous work to higher rotational $levels.^{1}$ Other lines correspond to the $v_{2} + v_{3} \leftarrow v_{2}, v_{3} + v_{4}(l=2) \leftarrow v_{4}$ and $v_{3} + v_{4} (l=0) \leftarrow v_{4}$ hot bands, which are complicated by large Coriolis interaction due to the near degeneracy of $v_{2}$ and $v_{4}$. Their analysis is underway. URI: http://hdl.handle.net/1811/12695 Other Identifiers: 1992-MF-07
