November 1, 2002
Author(s)
Askar Fahr, D C. Tardy
Rate constant and products of vinyl (H 2C=CH) and ethyl (C 2H 5) cross-radical reactions have been determined at ambient temperature and 93 kPa (700 Torr) pressure. Vinyl and ethyl radicals were produced simultaneously through the 193-nm excimer laser

The Crystal Structure of Chorismate Lyase Shows a New Fold and a Tightly Retained Product
