The Chemistry, Kinetics, and Mechanisms of Triplet Carbene Processes in Low-Temperature Glasses andrix isolation EPR spectroscopy in the study of triplet carbenes. Triplet carbenes are, of course, highly reactive intermediates formed upon photolysis of diazo compounds or diazirines. As such, they cannot be isolated and analyzed by conventional methods as can kinetically stable species. By photoch

Laser Flash Photolytic Studies of Arylhalocarbenes,s to . and .-butene, electrophilic selectivities toward alkenes, and an absence of hydrogen abstraction or other radical reactions are normative.. Even such a “loaded” case as .-F.CC.H.CBr shows no EPR signals in matrix isolation, and its UV spectrum is not quenched in O.-saturated methanol (see bel

Laser Flash Photolysis Studies of Triplet Carbenes,e seminal experiment was performed by Closs and Rabinow in 1976.. Using a very inexpensive and even primitive conventional flash lamp system, they obtained the first absolute rate constant for a carbene reaction in solution. Subsequent investigators using equipment that was much more sophisticated a

Solution Photochemistry of Carbenes and Biradicals,rea has been made possible by recent advances in laser photolysis techniques. While excited reaction intermediates can in some cases be generated by singlepulse excitation, this approach is far from ideal for the study of these systems. Two-laser, two-color techniques, which are extensively used in
