Abstract
An excimer laser operating at 193 nm has been coupled with the matrix isolation technique for the synthesis of chemical intermediates. Test systems included (CH 3) 3N, which yielded CH 4 and H 2CNCH 3 upon irradiation, likely by the photodetachment of a methyl group followed by hydrogen atom abstract within the matrix cage. Simple oxygen atom reactions were also examined, after irradiation of O 2 samples in argon and nitrogen matrices. No temperature or pressure rise was noted during irradiation, at repetition rate of 5–10 Hz, and no evidence for matrix damage or annealing was observed.
