One- and two-dimensional Fourier transform spectroscopy in the microwave and radiofrequency range of trifluoromethane in the vibrational state ν6 = 1

摘要: Abstract For trifluoromethane, CF 3 H, A 1 -A 2 splittings with K = | k - l in the degenerate vibrational state ν 6 have been determined using two-dimensional radiofrequency-microwave double resonance Fourier transform spectroscopy. The observation of direct -type transitions has extended to lower J values by means microwave analysis yielded improved for rotational constant C , Δ 0, ± interaction w and enabled determination a dependence 2, ∓ 4 t constant.
