摘要：

The high resolution Fourier transform infrared (FTIR) spectrum of the v(3) band of DCOOH has been measured with a resolution of 0.004 cm(-1) in the spectral range 1670-1810 cm(-1). Using the Watson's A -reduced Hamiltonian in the I-r representation, 713 infrared transitions have been assigned and fitted to provide rovibrational constants for the v(3) = 1 stare with a standard deviation of 0.000439 cm(-1). The v(3) band centre was found at 1725.87497 +/- 0.00003 cm(-1). The band is perturbed by the 2v(8) band, situated at 1762.9 cm(-1), through Fermi resonance and possibly a Coriolis term. Perturbations of v(3) by v(5) + v(7) and v(5) + v(9) are also expected. About 280 perturbed v(3) lines were identified and excluded in the final fit. (C) 1999 Elsevier Science B.V.
