摘要: Abstract Direct measurement by a laser pulse technique provides value for the lifetime of 1 Δ molecular oxygen in methanol τ = 7 ± μsec. Absolute reaction rate constants k A × 10 8 M −1 sec and 4 are obtained singlet acceptors, 1,3-diphenylisobenzofuran tetramethylethylene respectively. Additional acceptor may be calculated reference to published β values.
