Abstract
Near IR spectra (700-930 nm) were recorded from the head of anesthetized rats before and after blood substitution with a fluorocarbon emulsion. A large band, centered at 850 nm and characteristic of oxidized cytochrome .alpha.,.alpha.3, was evidenced in hemoglobin-free living animals. Variations in the amplitude of this absorption band were observed under different respiratory conditions.
