Abstract

Absorption, emission and CN fragment yield spectra of ethanedinitrile $(C 2 N 2$ ) have been measured between 225 and 206 nm. Even below the dissociation limit, emission is much stronger form the $A 1 Σ u −$ electronic state than the $B 1 Δ u$ electronic state. Conversely, the dissociation yield is higher from the $B 1 Δ u$ state than from the $A 1 Σ u −$ state. This allows us to distinguish between the two states. Absorption spectra have been taken for hot and cold samples which allows us to distinguish hot band absorptions. A tentative assignment for the region between 225 and 180 nm will be given.
