Abstract

The 308 nm excimer laser flash photolysis of 2-naphthyldiazomethane produces triplet 2- naphthylcarbene (λmax= 362 nm) which decays with the observed pseudo-first-order rate constants (kexptl) of 5.54±0.03× 106; 3.33±0.4× 106; 1.64±0.02× 107; and 3.05±0.4× 106 s- 1 in n-pentane, 2, 2, 4-trimethylpentane (2, 2, 4-TMP), benzene and Freon 113 respectively. In hydrocarbon solvents the observed decay of triplet 2-naphthylcarbene is correlated with ...
