The parallel band, 2 ν 3 , of CH 3 CD 3 is measured in the region 2715 to 2780 cm −1 under a spectral resolution of ∼0.025 cm −1 , increased to ∼0.015 cm −1 by deconvolution. About 460 lines are identified in the 2 ν 3 band, and about 240 lines in a hot band arising from the first excited torsional state. Least-squares analyses with Δ 2 F ″ combination differences yield lower-state parameters. An individual subband analysis is undertaken because of perturbations in the vibrational bands studied. Finally, band constants are derived. |
