摘要：

The transient light absorption changes at 400-600 nm observed following photodissociation of human adult carboxy-hemoglobin in aqueous solution (pH 7.0) by pulsed laser irradiation (7 ns fwhm, λ = 529 nm) reveal that geminate recombination is occurring during ≈ 100 ns after the dissociation. They also show that the spectrum of the photodeligated hemoglobin initially is slightly different from that of stable deoxyhemoglobin but develops into the latter in ≈5 μs. The recombination kinetics vary with the excitation condiitions (duration, intensity). © 1979.
