Photochemistry of Group V Ethyl-Containing Systems: Enhancing H-Atom Production via 248-nm Ethyl Radical Photolysis

Article abstract of DOI:10.1021/j100196a038

We report on the photolysis of triethylarsenic, monoethylamine, and monethylarsine with respect to H-atom formation.For all three molecules, 193-nm excitation followed by a 248-nm laser pulse produces an H-atom signal that is enhanced relative to the signal derived from the sum of the two lasers operating alone.The use of the selectively-deuterated compounds C2D5NH2 and C2H5ND2 clearly demonstrates that significant H-atom enhancement occurs via the ethyl group, at least in the case of monoethylamine.The importance of such photolysis reactions is discussed in terms of the laser-enhanced growth of III-V semiconductor materials.
