Line Intensities of CH3D in the Triad Region: 6-10 mu m
Line intensities of the three fundamentals of the 12CH3D Triad are modeled with an RMS of 3.2% using over 2100 observed values retrieved by multispectrum fitting of enriched sample spectra recorded with two Fourier transform spectrometers. The band strengths of the Triad in units of 10-18 cm-1/(molecule cm-2) at 296 K are, respectively, 2.33 for v6 (E) at 1161 cm-1, 1.75 for v3 (A1) at 1307 cm-1 and 0.571 for v5 (E) at 1472 cm-1. The total calculated absorption arising from 12CH3D Triad fundamentals is 4.65x10-18 cm-1/molecule cm-2) at 296K. In addition, some 740 intensities of nine hotbands are fitted to 8.1%; most of the hotband measurements belong to 2v6-v6 and v3+v6-v3 near 1160 cm-1, 2v3-v3 near 1304 cm-1. The other observed hotbands are v5 + v6-v6 2v5-v5, v5+v6-v5, v3+v5-v3, and v3+v5-v5.
