Based on the direct measurements of <jats:italic>\u03c4<\/jats:italic><jats:sub>T<jats:italic>n<\/jats:italic><\/jats:sub> of BP(T<jats:sub><jats:italic>n<\/jats:italic><\/jats:sub>), the triplet energy transfer (TET) from BP(T<jats:sub><jats:italic>n<\/jats:italic><\/jats:sub>) to quenchers (Q), such as carbon tetrachloride (CCl<jats:sub>4<\/jats:sub>), benzene (Bz), and <jats:italic>p<\/jats:italic>\u2010dichlorbenzene (DCB), was investigated. The fast TET from BP(T<jats:sub><jats:italic>n<\/jats:italic><\/jats:sub>) to Q can be attributed to the lifetime\u2010dependent quenching process, according to the Ware theoretical model of the bimolecular energy transfer reaction. The contribution of the lifetime\u2010dependent term on <jats:italic>k<\/jats:italic><jats:sub>TET<\/jats:sub> was 27, 60, and 86\u2009% for CCl<jats:sub>4<\/jats:sub>, Bz, and DCB as the Q of BP(T<jats:sub><jats:italic>n<\/jats:italic><\/jats:sub>), respectively, indicating that the TET from BP(T<jats:sub><jats:italic>n<\/jats:italic><\/jats:sub>) to Q is influenced not only by <jats:italic>\u03c4<\/jats:italic><jats:sub>T<jats:italic>n<\/jats:italic><\/jats:sub>, but also by the size of Q.<\/jats:p>","DOI":"10.1002\/chem.200500463","type":"journal-article","created":{"date-parts":[[2005,8,3]],"date-time":"2005-08-03T18:54:24Z","timestamp":1123095264000},"page":"6471-6477","source":"Crossref","is-referenced-by-count":34,"title":["Higher Triplet Excited States of Benzophenones and Bimolecular Triplet Energy Transfer Measured by Using Nanosecond\u2013Picosecond Two\u2010Color\/Two\u2010Laser Flash Photolysis"],"prefix":"10.1002","volume":"11","author":[{"given":"Xichen","family":"Cai","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masanori","family":"Sakamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mamoru","family":"Fujitsuka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuro","family":"Majima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,10,26]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja01240a030"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja01532a060"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1063\/1.1730987"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1039\/TF9635902038"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja00888a009"},{"key":"e_1_2_6_6_2","doi-asserted-by":"crossref","first-page":"241","DOI":"10.1002\/9780470133330.ch4","volume":"3","author":"Wilkinson F.","year":"1964","journal-title":"Adv.
