Journal ArticleDOI
Spectroscopy of Alkali Atoms (Li, Na, K) Attached to Large Helium Clusters
Frank Stienkemeier,John A. Higgins,Carlo Callegari,S. I. Kanorsky,Wolfgang Ernst,Giacinto Scoles +5 more
TL;DR: In this paper, the authors calculate the transitions within an approach based on the hypothesis that the chromophores are trapped in a dimple on the cluster surface as predicted by the theoretical calculations of Ancilotto et al.
Journal ArticleDOI
Photoinduced Chemical Dynamics of High-Spin Alkali Trimers
John B. Higgins,Carlo Callegari,James Reho,Frank Stienkemeier,Wolfgang Ernst,Kevin K. Lehmann,Maciej Gutowski,Giacinto Scoles +7 more
TL;DR: In this article, a nanometer-sized helium droplets were used as an inert substrate on which to form spin-3/2 (quartet state) trimers, which undergo intersystem crossing to the doublet manifold and then dissociation into an atom and a covalently bound singlet dimer.
Journal ArticleDOI
Helium cluster isolation spectroscopy of alkali dimers in the triplet manifold
John A. Higgins,Carlo Callegari,James Reho,Frank Stienkemeier,Wolfgang Ernst,Maciej Gutowski,Giacinto Scoles +6 more
TL;DR: Helium cluster isolation spectroscopy is a recently developed spectroscopic method that involves the formation of a beam of large helium clusters (104 atoms per cluster), the capture by the cluster...

Dipole Moments and Potential Energies of the Alkaline Earth Monohalides from an Ionic Model
TL;DR: In this article, it was shown that the Rittner model is inadequate for the calculation of dipole moments for the alkaline earth monohalides and a modified model was proposed which takes into account explicitly the large charge shifts in the metal ions arising from the polarization.
