    We present a photolysis study of pyrrole, imidazole and pyrazole clusters in comparison to the photolysis of the isolated molecules. Size distributions of different mean cluster sizes have been prepared and characterized in supersonic expansions. The clusters were photolyzed at 243 and 193 nm and the kinetic energy distributions (KEDs) of the H-fragments were measured. The KEDs of all systems exhibit a bimodal character with slow and fast H-fragment peaks similar to the spectra of the corresponding single molecules. However, with the increasing clusters size the slow component gains on intensity in comparison to the fast component. A similar effect is observed with increasing the excitation energy from 243 to 193 nm.
