Valence-bond Non-equilibrium Solvation Model for a Twisting Monomethine Cyanine
Sean McConnell, Ross H. McKenzie, Seth Olsen
We propose and analyze a two-state valence-bond model of non-equilibrium solvation effects on the excited-state twisting reaction of monomethine cyanines. Suppression of this react…
Canonical-ensemble SA-CASSCF strategy for problems with more diabatic than adiabatic states: Charge-bond resonance in monomethine cyanines
Seth Olsen
This paper reviews basic results from a theory of the classical probabilities in state-averaged complete active space self-consistent field wave functions. It is proposed that a ca…
A two-state model of twisted intramolecular chargetransfer in monomethine dyes
Seth Olsen, Ross H. McKenzie
A two-state model Hamiltonian is proposed to model the coupling of twisting displacements to charge-transfer behavior in the ground and excited states of a general monomethine dye…
An Effective Hamiltonian for Symmetric Diarylmethanes from a Series of Analogous Quantum Chemical Models
Seth Olsen, Ross H. McKenzie
We propose a single effective Hamiltonian to describe the low-energy electronic structure of a series of symmetric cationic diarylmethanes, which are all bridge-substituted derivat…
Bond Alternation, Polarizability and Resonance Detuning in Methine Dyes
Seth Olsen, Ross H. McKenzie
We derive structure-property relationships for methine ("Brooker") dyes relating the color of the dye and its symmetric parents to its bond alternation in the ground state and also…
A Dark Excited State of Fluorescent Protein Chromophores, Considered as Brooker Dyes
Seth Olsen, Ross H. McKenzie
The green fluorescent protein (GFP) chromophore is an asymmetric monomethine dye system. In the resonance color theory of dyes, a strong optical excitation arises from interactions…
