【Abstract】 A photoacoustic detection system consisted of a piezoelectric cylindrical tube trans-ducer is applied to measure the photolysis of Coenzyme B12 (5’-deoxyadenosylcobalamin, AdoCbl)in methanol to obtain the quantum yield, φ. The value of 0.20±0.05 is in agreement with that obtained in aqueous solution by other authors with an optical method.
