Abstract

¹²C₂ and ¹³C₂ were efficiently produced by a dc discharge of H¹²CN, H¹³CN and ¹²C₂H₂ and their matrix absorption and emission spectra in the infrared and the near-infrared region have been studied. Laser excitation of the 2-0 and 3-0 A ¹Π_u← X¹Σ⁺_g Phillips bands leads to both A ¹Π_u → X¹Σ⁺_g emission, as well as to be ³Σ^-_g →a ³Π _u fluorescence resulting from nonradiative intersystem crossing. Consecutive two-photon absorption results in a strong blue emission in the visible attributable to the d³Π_g →a ³Π_u Swan system. The spectroscopic constants for all the observed states in solid neon have been obtained and compared with the values in the gas phase. The relaxation mechanisms leading to population of the b ³Σ^-_g state are discussed.
