LINE INTENSITIES AND ASSIGNMENTS FOR THE $\nu_{3} + \nu_{4} - \nu_{4}$ BAND OF METHANE

Author Institution: Department of Physics, The Florida State University; Jet Propulsion Laboratory, The Florida State University; Institute for Physical Science and Technology, University of MarylandThe recent analysis of $\nu_{3} + \nu_{4}$ of methane by Bobin and Moret-Bailly when combined with previous analyses of $\nu_{4}$ allows a direct calculation of the line positions of the ``hot” band $\nu_{3} + \nu_{4} - \nu_{4}$. A considerable number of lines of this band have been observed in our $0.020\, cm^{-1}$ resolution intensity data in the $3.3\,\mu m$ region. Measurements of the line intensities at several temperatures yield energy values for the initial states of the transitions which serve to confirm the assignments
