摘要

Results The 308-nm laser flash photolysis (LFP) of a deoxygenated acetonitrilc solution of bis (methanesulfony1) peroxide, 3a,(0.2 M) at 18 “C yielded “instantaneously”(Le., within 4 ns, the full width at half-height of the laser pulse) a broad, transient absorption (half-width ca. IIO nm) with a maximum at ca. 450 nm and a broad, much weaker maximum at ca. 570 nm (Figure 1). Both the 450-and 570-nm absorptions decayed by a (pseudo-) first-order ...
