Cluster‐Controlled Photofragmentation: The Case of the Xe–Pyrrole Cluster

Photodissociation of Molecules in Pure and Doped Water and in Nitrogen Heterocyclic Clusters in the Excited State

“…The spectra have been analysed and deconvoluted to the contributions of the two components (red and blue lines in Figure 39.17). Similar spectra have also been measured for the bare pyrrole [96][97][98][99][100][101] and imidazole [87] molecules. The relative ratio of the two contributions changes with the cluster size.…”

“…Note that a very similar effect has also been observed at the same time in the group of Kitsopoulos [100,101] by solvating the pyrrole molecule with a single Xe atom. The pp * =S 0 intersection remains open and the population of the slow peak is not hindered.…”

“…Already from Figure 39.17 it is obvious that the fast component decreases in intensity relative to the slow one with increasing mean cluster size. [87,[96][97][98][99][100][101]. [87,[96][97][98][99][100][101].…”

Structural dynamics of 4‐formaldehyde imidazole and imidazole in light absorbing S2(ππ*) state

“…Hydrogen dissociation on the πσ * state is considered to be a representative model to photophysics of many heteroaromatic molecules in the gas phase . However, this gas phase model is challenged in solution by the fact that direct dissociation along the πσ * reaction channel of the heteroaromatic molecule (such as imidazole and pyrrole) is suppressed by the coordinated matrix molecules such as Ar and water . Experiment setup of resonance Raman spectroscopy in conjunction with the matrix isolation technique is currently under construction in our laboratory.…”

New Academicians of the Chinese Academy of Sciences

“…Yang’s research covers the kinetics and dynamics of chemical reactions, including unimolecular photodissociation and bimolecular reactions. He has reported on photofragmentation in Xe–pyrrole clusters in ChemPhysChem 5…”
