✦ Synopsis

Theoretical and experimental evidence is collected which indicates that the upper level of the Cz high-pressure bands (d 'D, (v' = 6) +a 31T,) is populated via a potential-curve crossing by the metastable state ?&. This metastable state is populated preferentially during formation of Cz from free carbon atoms.

The origin of C2 high-pressure bands observed in discharges through CO has not been cleared up. The suggestion by Little and Browne of a collisional transfer between the metastable CI('l&, u=O) and the radiative Cz(d 3TI,, ~6) level was progress. However, these authors claimed that only the combinat
