Two conformers of ClCOOH were produced upon irradiation at 355 nm of a gaseous flowing mixture of Cl_{2}, HCOOH, and N_{2}. A step-scan Fourier-transform infrared spectrometer coupled with a multipass absorption cell was utilized to monitor the transient spectra of ClCOOH. Absorption bands with origins at 1808.0 and 1328.5 cm^{-1} are attributed to the C=O stretching and COH bending modes of {t}-ClCOOH, respectively; those at 1883.0 and 1284.9 cm^{-1} are assigned as the C=O stretching and COH bending modes of {c}-ClCOOH, respectively. These observed vibrational wavenumbers agree with corresponding values for {t}-ClCOOH and {c}-ClCOOH predicted with B3LYP/aug-cc-pVTZ density-functional theory and the observed rotational contours agree satisfactorily with simulated bands based on predicted rotational parameters. The observed relative intensities indicate that {t}-ClCOOH is more stable than {c}-ClCOOH by 3 kJ mol^{-1}. A simple kinetic model is employed to account for the production and decay of ClCOOH.
