| abstract |
The photochemical rearrangement of quinoxaline-1,4-dioxide (1) was studied in an aqueous solution. Three types of transient absorption spectrum in addition to the triplet-triplet absorption spectrum were observed by conventional flash photolysis. One transient, designated 2, observed in the neutral solution was assigned to the oxaziridine intermediate. Two transients, designated 5 and 6, were observed in the acidic solution. 5 was tentatively assigned as the protonated form of 2. |

Three types of transient absorption spectrum in addition to the triplet-triplet absorption spectrum were observed by conventional flash photolysis. One transient, designated 2, observed in the neutral solution was assigned to the oxaziridine intermediate. Two transients, designated 5 and 6, were observed in the acidic solution. 5 was tentatively assigned as the protonated form of 2.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kawata, H.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kikuchi, K.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kokubun, H.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Journal of Photochemistry</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">21(1983), 4, Seite 343-350</subfield><subfield code="w">(DE-627)NLEJ174709595</subfield><subfield code="w">(DE-600)2198720-8</subfield><subfield code="x">0047-2670</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:21</subfield><subfield code="g">year:1983</subfield><subfield code="g">number:4</subfield><subfield code="g">pages:343-350</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0047-2670(83)87119-6</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">21</subfield><subfield code="j">1983</subfield><subfield code="e">4</subfield><subfield code="h">343-350</subfield></datafield></record></collection>
