| Abstract: | A parallel band at 2,200 cm−1 and a perpendicular band at 2,780cm−1 of CH3D have been observed under high resolution andanalysed. The analysis of the perpendicular band revealed the presence of l-type doublingin the doubly degenerate excited state. From the analysis of the parallel band it is foundthat B0= 3.880 cm−1. A hybrid band ofCD3H has been observed near 2,600 cm−1. Both activecomponents, A and E are observed and analysed. Theground state B0 value found from this analysis is in goodagreement with previous determinations. |
