The transient grating (TG) method has been applied to studies on the photolysis quantum yield (φ<SUB>d</SUB>) of iodine and diphenyl disulfide in supercritical fluids. The solvent density dependence of φ<SUB>d</SUB> for iodine obtained by the TG method is quite different from the result by the transient absorption method (B. Otto, et al., J. Phys Chem., 81, 202 (1984) ), if the TG signal is analyzed only by the thermal grating contribution. If we assume that the difference comes from the overestimate of φ<SUB>d</SUB> from the TG method, the origin could be ascribed to the neglect of volume grating term. Underr this assumption, the estimated reaction volume for the dissociation of iodine should be a considerably large negative over the density regions studied.
