AbstractA detailed study was explored to compare the transient absorption spectra of the neat 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]) with its solution in water or acetonitrile. It was concluded that the excited triplet state (3)[bmim](+center dot) was produced after 266 nm laser irradiation, and then the neutral radical [bmim](center dot) and the cation radical [bmim](2+center dot) were formed through two possible paths. The transient absorption spectra of the neat [bmim][BF4] and its solution were similar but the reaction kinetics were different due to their different local structures such as dimeric or cluster. The energy transfer between excited [bmim][BF4]] and beta-carotene further affirmed the existence of (3)[bmim](+center dot). And the reaction that the hydrated electron captured by [bmim](+) to produce [bmim](center dot) in solution was observed. (C) 2011 Elsevier B.V. All rights reserved.
