摘要：

Absorption cross-sections of the vinyl radical (C2H3) have been determined in the spectral range 440-460 nm, using laser photolysis coupled with a cavity ring-down spectroscopic detection technique. The disappearance rate of vinyl radical by its absorption in (A) over tilde(2)A "-(X) over tilde(2)A' transition was probed by visible cavity ring-down spectroscopy. Based on a reaction kinetics simulation, the absorption cross-sections of the vinyl radical were estimated. (C) 1999 Elsevier Science B.V. All rights reserved.
