Sequential biphotonic processes in phthalocyanines, pc, have been investigated in irradiations with two trains of monochromatic pulses. The pulses of one train lambda = 640 nm, were used for the generation of (/sup 3/..pi pi..*)Al(pc)Cl. The pulses of the other lambda = 490 nm and delayed by 0 less than or equal to delta less than or equal to 2 ms with respect to the 640-nm pulses, were used for the photolysis of this state. A direct relationship between the yield of the biphotonic process and the delay time delta was found to be in agreement with a proposed mechanism for the dichromatic-biphotonic photochemistry. 9 references, 2 figures.
