Photoinduced chemical reactions of 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF_6]) were studied by laser photolysis at a wavelength of 266 nm.Excited triplet state ~3[bmim]~+ was observed,radical cation [bmim]~(2+) and neutral [bmim] radical via photoionization were also formed.Energy transfer from ~3[bmim]~+ toβ-carotene was confirmed.Oxidation via one electron transfer from TMPD to ~3[bmim]~+ was also observed and the rate constant was determined to be 1.2×10.5 L.mol~(-1).s~(-1).The reaction of [bmim][PF_6] with hydrated electron (e_(aq)) was confirmed by laser photolysis in aqueous solution.

Extited triplet state ~ 3 [bmim] ~ 2+ and neutral [bmim] radical via photoionization were also formed. Energy transfer from ~ 3 [bmim] ~ + toβ-carotene was confirmed. One via one electron transfer from TMPD to ~ 3 [bmim] ~ + was also The reaction of [bmim] [PF_6] with hydrated electron (e_ (aq)) was confirmed to be 1.2 × 10.5 L.mol -1 (-1) .s -1 photolysis in aqueous solution.
