Excimers

Birks, J B·1975·Reports on Progress in Physics

Abstract

Excimers are dimers with associated excited electronic states, dissociative ground states, and structureless emission spectra. Noble and other monatomic gases form atomic excimers. Aromatic molecules form excimers in fluid solutions, liquids, crystals and polymers, at crystal defects, and intramolecularly. Excimer interaction is attributed to configurational mixing of exciton and charge resonance states. The helium excimer and pyrene crystal dimer potential curves are compared. Aromatic excimers are discussed. Related photophysical studies on atomic excimers are considered. Saturated amines, which exhibit vapour and solution excimer fluorescence, provide a link between atomic and aromatic excimers. Aromatic molecules form complexes, exciplexes or mixed excimers with different molecules, and noble gas atoms form complexes or exciplexes with different atoms. Review completed in 1975.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
