 Title: LINE ASSIGNMENTS AND INTENSITIES FOR THE $\nu_{2} + \nu_{4}$ BAND OF METHANE Creators: Brown, L. R.; Toth, R. A.; Hunt, R. H.; Robiette, A. G. Issue Date: 1978 Publisher: Ohio State University Abstract: The forbidden transitions have been identified and allowed transitions assignments extended for the $\nu_{2} + \nu_{4}$ band of $CH_{4}$ using spectra recorded at $0.023\, cm^{-1}$ resolution with the four-pass grating spectrometer at Florida State University. The assignment process has been greatly aided by the measurement of individual line strengths at different temperatures to obtain experimental values for the ground state energy levels of the transitions. Corresponding allowed transitions of $\nu_{2} + \nu_{4}$ of $^{13}CH_{4}$ have been identified.
