Abstract: | The CHD3 Raman spectrum from 1925 to 2455 cm?1 has been photographed with a resolution of about 0.2 cm?1, showing the overlapping ν2 and ν4 bands. Ground state combination differences yield C0 = 2.6297 ± 0.0003 cm?1. The ν4 state is weakly perturbed, but reasonably accurate values could be obtained for ν4 = 2250.88 ± 0.10 cm?1, (Cζ)4 = 0.656 ± 0.010 cm?1, C4 - C0 and B4 - B0. Some of these constants differ significantly from values previously estimated by infrared workers. For the ν2 state the constants determined are in good agreement with recent infrared results. |
