✦ Synopsis
The cross section for electronic quenching of the B 'E+ state of CO has been measured after a two-step excitation via the intermediate A III state by the subsequent fluorescence from the final excited B 'E+ state back down to the X iZ+ ground state and from its pressure dependence. In the case of the B ix+ state, the measured quenching cross section for hydrogen of 20 A* is at least an order of magnitude larger than that for helium suggesting the formation of an excited collisional CO-H2 complex.
