High resolution synchrotron far-infrared study of CH2D79Br: The v6 fundamental and 2v6 − v6, v5 + v6 − v6 and v6 + v9 − v6 hot bands

The high resolution (0.0025 cm−1) far-infrared absorption spectrum for the v6 (v0 = 595.0733 cm−1) fundamental band of CH2D79Br has been recorded by Fourier transform spectroscopy employing a synchrotron radiation source. The spectral analysis allowed the assignment of more than 1700 rovibrational transitions attributed to the predominant a-type component. In the same spectral range, the 2v6 − v6 hot band has been analyzed by selecting about 800 transitions. In addition, hot band transitions originating from v6 have been assigned in region of the v5 and v9 fundamentals. The data set of each band was treated using the Watson’s A-reduced Hamiltonian in the Ir representation.
