Fast Evaluation of Geometries and Properties of Excited Molecules in Solution: A Tamm-Dancoff Model with Application to 4-Dimethylaminobenzonitrile
Abstract
We present a method to evaluate ab initio energy, wave function, and gradient of a solvated molecule in an electronically excited state. In particular, this paper extends the Polarizable Continuum Model (PCM) to a specific level of theory for the interpretation of the electronic spectra: configuration interaction (CI) among all singly substituted determinants using a Hartree−Fock reference state. This method, in very wide use, allows investigations of both structures and properties of electronically excited molecules through the evaluation of analytical energy derivatives with respect to various parameters. The most relevant formal aspects on the extension of the theory to solvated systems are discussed, and numerical applications to the study of geometries and one-electron properties of the low-lying excited states of 4-dimethylamino benzonitrile (DMABN) in acetonitrile solution are presented.

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.
