Abstract
The A2Σ+ -X2II1(a) absorption system of the NCO free radical has been re-investigated with higher resolving power than in the earlier work of Dixon (i960). Particular emphasis has been directed to the rotational analyses of bands involving the three vibronic levels, μ2Σ(+), 2Δi-(a) and k2Σ(-), associated with the first level of the bending vibration in the ground state. A misassignment in the earlier work has been corrected and a new value for the Renner parameter determined, namely ε = -0.144 ± 0.001. This revised value removes the discrepancy noted in the earlier electron resonance results.Keywords
