Radiative lifetime of the A^2Δ state of CH†

Abstract

The lifetime of various rotational levels of the v′ = 0 and 1 vibrational states of the A²Δ state of CH are reported. The lifetimes for the various levels were nearly constant with the rotational quantum number N′. For the v′ = 0 level it was 508 ± 25 ns and for the v′ = 1 level, it was 514 ± 33 ns. The bandhead lifetime was 500 ns and these lifetimes are very close to the bandhead lifetime.
