✦ Synopsis

High-resolution infrared spectra of the low-lying (\nu_{3}, \nu_{4}), and (\nu_{5}) fundamentals of the transient molecule DCOCl are reported. These type- (A / B) hybrid bands have been analyzed in detail, providing extensive rotational assignments for the (\mathrm{DCO}^{35} \mathrm{Cl}) and (\mathrm{DCO}^{37} \mathrm{Cl}) isotopomers. The ground state constants have been refined by a simultaneous fit of the available microwave data and FTIR combination differences from the three bands. The excited state constants have been determined by fitting assignments over a wide range of (J) and (K_{a}) values. A small perturbation was found at high (K_{a}) values in the (v_{4}) band and determined to be due to a (\Delta K_{a}=-2) interaction with the rotational levels of the (6^{1}) vibrational state.
