A parallel band at 2,200 cm -1 and a perpendicular band at 2,780 cm -1 of CH 3 D have been observed under high resolution and analysed. The analysis of the perpendicular band revealed the presence of l-type doubling in the doubly degenerate excited state. From the analysis of the parallel band it is found that B 0 = 3.880 cm -1 . A hybrid band of CD 3 H has been observed near 2,600 cm -1 . Both active components, A and E are observed and analysed. The ground state B 0 value found from this analysis is in good agreement with previous determinations.
