Abstract: The high resolution Fourier transform infrared (FTIR) spectrum of the v3 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 Ir representation, 713 infrared transitions have been assigned and fitted to provide rovibrational constants for the v3 = 1 state with a standard deviation of 0.000439 cm-1. The v3 band centre was found at 1725.87497±0.00003 cm-1. The band is perturbed by the 2v8 band, situated at 1762.9 cm-1, through Fermi resonance and possibly a Coriolis term. Perturbations of v3 by v5+v7 and v5+v9 are also expected. About 280 perturbed v3 lines were identified and excluded in the final fit.
