This process utilized the analysis of $\nu_{2}+\nu_{3}$ at $4544 cm^{-1}$ by Hilico et. al. and the $\nu_{2}$ levels derived from the infrared spectrum by Margolis to predict the positions of the hot band. Experimentally determined lower state energies have been used to confirm assignments, and room temperature line intensities are observed on the order of $10^{-3}$ $cm^{-2}$ $atm^{-1}$ or less. At each J, the strongest hot band P branch lines occur at the highest energy levels of $\nu_{2} + \nu_{3}$, While the strongest R branch lines occur at the lowest levels. These data indicate a selection rule of $\Delta_{E} = 0$ hand also $\Delta N_{E} = 0$ for this hot band. en_US dc.format.extent 95062 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.title LINE ASSIGNMENTS AND INTENSITES OF THE $\nu_{2}+\nu_{3}-\nu_{2}$ HOT BAND OF $CH_{4}$ at $3010 cm^{-1}$ en_US dc.type article en_US
