摘要：

The v(12) band of trans-d(2)-ethylene (trans-C2H2D2) has been recorded with an unapodized resolution of 0.0024 cm(-1) in the frequency range of 1240-1360 cm(-1) by Fourier transform infrared (FTIR) spectroscopy. This band was found to be relatively free from any local frequency perturbations. By fitting a total of 1185 infrared transitions of v(12) with a standard deviation of 0.00043 cm(-1) using a Watson's A-reduced Hamiltonian in the I-r representation, a set of accurate rovibrational constants for v(12) = 1 state was derived. The v(12) band is A type with a band center at 1298.03797 +/- 0.00004 cm(-1). (C) 2000 Academic Press.
