    • Although the transient absorption of 2(5 H)-furanone triplet state in acetone is found to peak at ∼360 nm, this species gives rise to a residual absorption signal at 302 nm, whose intensity is much lower than that of ethylene triplet state but rises with increasing concentration of 2(5 H)-furanone until a significant contribution to the overall decay trace is displayed at this wavelength. It is important to note that 2(5 H)-furanone triplet state may be generated both by direct absorption of the lactone at 266 nm and sensitization via ethylene triplet state
