The high-resolution Fourier transform spectrum of the DO35Cl molecule was recorded and analyzed in the region of the two lowest D-O overtone bands, 2v1 and 3v1. Because of the presence of strong resonance interactions, the influence of the (130) state on the (200) state, and also that of the (221), (230) states on the (300) sate, was taken into account. Transitions belonging to the 2v1 and 3v1 bands were assigned up to Jmax = 35 in both cases. The sets of spectroscopic parameters and resonance coefficients obtained from the fit reproduce the "experimental" rovibrational energies of the (200) and (300) vibrational states with accuracies close to experimental uncertainties.
