For comparison, spectra were also calculated for an isolated Cl2 molecule as well as for selected Cl2(H2O)n, n ≤ 8, clusters cut out of the Cl2(H2O)2O cluster, allowing us to follow the evolution of the low-lying excited states with increasing number of surrounding water molecules. Although encapsulation of a chlorine molecule within the water cages has relatively little effect on its low-lying valence transitions, it does result in a large number of solvent-to-solute charge-transfer transitions at energies starting near 48 000 cm-1. © 2007 American Chemical Society. date: 2007-08-16 type: Article type: PeerReviewed format: text/plain language: en rights: attached identifier: http://d-scholarship-dev.library.pitt.edu/16083/1/licence.txt identifier: Schofield, DP and Jordan, KD (2007) Theoretical investigation of the electronically excited states of chlorine hydrate.
