photolysis of an isolated pyrrole molecule. Experimentally, size distributions of different
mean cluster sizes ( n= 3 and n⪢ 5) have been prepared in supersonic expansions and
the clusters were photolyzed at 243 and 193 nm. The kinetic energy distributions of the H
photofragments have been measured. The distributions exhibit a bimodal character with fast
and slow H-fragment peaks similar to the spectra of the bare molecule. However, with …
