Exciton energy transfer reveals spectral signatures of excited states in clusters

Abstract

<p>Electronic excitation and concomitant energy transfer leading to Penning ionization in argon–acetylene clusters are investigated with synchrotron-based photoionization mass spectrometry and electronic structure calculations.</p>

A combined theoretical and experimental study of small anthracene–water clusters

“…Previously we have demonstrated that smaller nozzle sizes and larger backing pressures could give rise to formation of large argon clusters which could skew the dynamics of cluster formation. 37,38 The inset of Fig. 1A shows an expanded region of the mass spectrum between 213 and 220 m/z.…”

Proton Transfer in Nitromethane–Ammonia Clusters under VUV Single-Photon Ionization Explored by Infrared Spectroscopy and Theoretical Calculations

“…The detailed experimental setups have been described previously; − only a brief description is given here. Gas-phase CH 3 NO 2 -NH 3 clusters are generally produced in supersonic jet expansion. − The mixture of ammonia and helium (He) was used as the carrier gas, and the concentration of ammonia is 5%. The pressure was about 0.2 MPa.…”

Reaction dynamics within a cluster environment

“…A process of this type has been explored experimentally and documented theoretically by Musahid Ahmed and coworkers in Ar E20 clusters hosting either (H 2 O) 1-9 complexes or a C 2 H 2 molecule. 115,116 The experiments were performed at the Chemical Dynamics Beamline at the Berkeley Advance Light Source (ALS). 29 The clusters were generated by continuous supersonic expansion of argon mixed with guest molecules.…”
