✦ Synopsis

The chemiluminescent reaction C1+3H2(X '2: ) -H('S,) tHCI+(A *Z+) has been observed in an ion-molecule scattering experiment. This was achieved by detection of the spontaneous optical emission of the HCI+( A *Z*, u' =0+X *Ui, u" =0) band in the wavelength region between 3500 and 3650 A. The reaction produces only a very low luminescence intensity, from which a cross section of the order of 4x 10e3 A' was estimated. This small cross section could be explained qualitatively by means of an ab initio correlation diagram of the H2CI' collision complex, which shows that only a small fraction of the ions of the entrance channel will react into the observed product state.

## Abstract The reaction Cl + H~2~CO → HCl + HCO has been studied at 295 K. Chlorine atoms were produced via the infrared laser induced dissociation of CCl~3~F, using a pulsed CO~2~ TEA laser. Using HCl infrared chemiluminescence as the diagnostic, we find the rate constant to be 7.4 ± 0.7 × 10^−11
