Abstract
The à 2Δ–X̃ 2Π electronic transition of the CCN free radical was observed in emission with a high‐resolution Fourier transform spectrometer. The CCN was jet‐cooled in a corona‐excited supersonic jet expansion of diazoacetonitrile (HC(N2)CN) in helium. From the 000–000, 000–001, 000–002, and 000–100 vibronic bands spectroscopic constants were derived including the ground‐state vibrational frequencies, ν3=1050.7636(6), 2ν3=2094.8157(18), and ν1=1923.2547(69) cm−1.Keywords
