Abstract
The photolysis of [human] HbO2 and HbCO was investigated with ps laser techniques. Transient absorption spectra were measured in the Soret and visible regions after excitation with 353- or 530-nm pulses. The photoproducts appeared within 8 ps and exhibited considerably broadened deoxyhemoglobin-like spectra, which persisted to 680 ps. The altered spectra were attributed to the production of deoxyheme conformational and spin states that might result from intense excitation.This publication has 22 references indexed in Scilit:
