✦ Synopsis
The kinetics of the quenching of metastable O,(b 'Xi.', molecules in collisions with Hz, D2, CO*, I-INS, DN3, HNCO, and DNCO was investigated in the temperature range 210-350 K. The corresponding rate constants are given. Small concentrations of O,(b) were generated in the VUV H2 laser photolysis of Or and detected by its time-resolved phosphorescence emission to the ground state.
