Competition between Photochemistry and Energy Transfer in Ultraviolet-Excited Diazabenzenes. 3. Photofragmentation and Collisional Quenching in Mixtures of 2-Methylpyrazine and Carbon Dioxide

The quantum yield for HCN formation via 248 and 266 nm photodissociation of methylpyrazine (C5N2H6) is determined by IR diode probing. HCN is produced at two different dissociation rates, one of which is extremely prompt. The total quantum yield is φ = 0.93 ± 0.08 for 248 nm and 0.35 ± 0.05 for 266...
