Photolysis of NO trapped in a rigid matrix at 6 K

Nitric oxide embedded in inert solvents has been photolyzed at low temperature (6 K) by different photon energies in the vacuum uv. In argon matrices, two emissions have been identified as the β bands, NO (B 2∏→x 2∏) and as a spin forbidden transition attributed to the M bands. In N2 matrix, only the β bands have been observed. In no case have transitions from Rydberg states been observed.
