The ultraviolet absorption spectrum of the F2CN radical

A new system of absorption bands near 3600 Å has been observed during the flash photolysis of CF3NCF2 and is ascribed to the free F2CN radical. The rotational analysis of the 0–0 band leads to the ground state molecular structure rCF = 1.310 Å (assumed), rCN = 1.265 ± 0.02 Å, FCF angle = 113.5 + 1°....

Description
Summary:A new system of absorption bands near 3600 Å has been observed during the flash photolysis of CF3NCF2 and is ascribed to the free F2CN radical. The rotational analysis of the 0–0 band leads to the ground state molecular structure rCF = 1.310 Å (assumed), rCN = 1.265 ± 0.02 Å, FCF angle = 113.5 + 1°. The bands are shown to be type A bands arising from the transition 2A1 ← 2B2, and the spectrum is compared with those of the iso-electronic molecules NO3 and F2BO.
