In a recent theoretical study Yurchenko et al. (1) assigned the near ultraviolet band system of methylene, that had been observed by Herzberg and Johns (2), as the c1 A 1 β ( Γ£1 A 1 / b1 B 1 ) band system. This assignment required that the c1 A 1 state be predissociated in order to account for the d

The specific decomposition rates of chemically activated methylcyclobutane produced from CH#Al) reaction with cyclobutane $ave been determined. CHz(lAl)was produced from ketene photolyses at 3340 and 3130 A and from diazomethane photolyses at 4358 and 3660 A. Comparisons of the excitation energies o
It is postulated that the collision-induced singlet-triplet transition of methylene involves coupling between the electronic orbital angular momenta of the inert catalyst and +he electron spins of methytene. A theory which incorporates this mechanism is presented and partialty tested.
