Enzymically generated triplet acetone

Abstract
The oxidation of isobutyraldehyde in the horseradish peroxidase–O2 system produces triplet acetone in high yield, as shown by efficiently sensitized 9,10-dibromoanthracene-2-sulphonate emission and by the occurrence of the expected photoproducts, i.e. isopropyl alcohol and tetramethylglycol.
