✦ Synopsis

The FTIR spectrum of the 6 band of H 13 COOH has been collected at a resolution of 0.004 cm Ϫ1 in the frequency range of 1030 -1160 cm Ϫ1 . The 6 band was analyzed to be an A-B hybrid band and perturbed by the nearby 8 band through a-, and b-Coriolis coupling terms. Using a Watson's A-reduced Hamiltonian in the I r representation, with the inclusion of a-and b-Coriolis resonances, a total of 3004 IR transitions of 6 have been analyzed to provide rovibrational constants for the v 6 ϭ 1 state with a standard deviation of 0.00047 cm Ϫ1 . The 6 band was found to be centered at 1095.40365 Ϯ 0.00003 cm Ϫ1 .

The high-resolution Fourier transform infrared spectrum of HCOOD has been measured in the 5 region between 1120 and 1220 cm Ϫ1 with a resolution of 0.004 cm Ϫ1 . As expected for an in-plane vibrational fundamental mode, the 5 band is a hybrid band consisting of both a-type and b-type transitions. Us
