The ultraviolet absorption spectrum of the F 2 CN radical

Abstract
A new system of absorption bands near 3600 Å has been observed during the flash photolysis of CF 3 NCF 2 and is ascribed to the free F 2 CN radical. The rotational analysis of the 0–0 band leads to the ground state molecular structure r CF = 1.310 Å (assumed), r CN = 1.265 ± 0.02 Å, FCF angle = 113.5 + 1°. The bands are shown to be type A bands arising from the transition 2 A 12 B 2 , and the spectrum is compared with those of the iso-electronic molecules NO 3 and F 2 BO.
