摘要: Abstract The photosensitized cis-trans isomerization of butene-2 in the presence sulphur dioxide excited within its first allowed absorption band has been examined. Isomerization results primarily from reaction triplet SO2 molecules (3SO2) with although there is some evidence for a singlet cis-2-butene leading to isomerization. quenching rate constants 3SO2 cis-butene-2 and trans-butene-2 relative were determined measurements quantum yields at high [SO2]/[butene-2] ratios. reaction: + (cis or trans) → SO2+x (1—x) 1.62 ± 0.08 × 1011 1 mol−1 s−1 cis isomer 1.42 0.09 trans based on literature value 3.9 108 absolute constant SO2. x, fraction formed isomerization, was 0.587 0.028. provides useful method determination photolysis band. At pressure wavelength used present study, yield production 0.112 0.006.
