Abstract
The radiative lifetimes of the N′=3 to 15 rotational states of the v′=0 level of the B 2Σ− state of CH were measured. Emission lines were observed to N′=15, but no lines above this rotational state were observed. This result agrees with previous studies. The lifetimes of all rotational states were between 300 and 400 ns. Previous measurements have indicated that the N′=15 level might have a lifetime as short as 100 ns.Keywords
