Theoretical studies on the electronically excited states of helium clusters

The vertical excited states of small helium clusters were calculated using configuration interaction singles (CIS) and the character of the states was determined from studying the attachment and detachment densities [2]. It was found that in the n=2 manifold of excited states the cluster excitations could be interpreted in terms of superpositions of atomic like states and good agreement with ex...

COMPUTATIONAL ENUMERATION OF POINT DEFECT CLUSTERS IN DOUBLE- LATTICE CRYSTALS

The cluster representation matrices have already been successfully used to enumerate close-packed vacancy clusters in all single-lattice crystals [I, 2]. Point defect clusters in double-lattice crystals may have identical geometry but are distinct due to unique atomic postions enclosing them. The method of representation matrices is extended to make it applicable to represent and enumerate ...

Electronically Excited States of Interstellar Anions

In the search for carriers of the diffuse interstellar bands (DIBs), a nearly ubiquitous, as-of-yet unattributed interstellar absorption spectrum, new theories are being proffered to explain this astronomical phenomenon. One of these is that rarely occurring excited states of anions may be responsible for some of these features. Using state-of-the-art quantum chemical techniques we examine near...

Performance with an electronically excited didgeridoo

The didgeridoo is a wind instrument composed of a single large tube often used as drone instrument for backing up the mids and lows of an ensemble. A didgeridoo is played by buzzing the lips and blowing air into the didgeridoo. To play a didgeridoo continously one can employ circular breathing but the volume of air required poses a real challenge to novice players. In this paper we replace the ...

Spectroscopy, polarization and nonadiabatic dynamics of electronically excited Ba(Ar)n clusters: Theory and experiment

Molecular Dynamics simulations using a surface-hopping method for transitions between different electronic states are employed to study the dynamics following photoexcitation of the Ba(Ar)125 cluster. The results are used to interpret spectroscopic experiments on large, size-distributed Ba(Ar)n clusters. The dynamics of the coupled electronic-nuclear motions in the cluster involves transitions ...
