Nuclear quantum effects on the non-adiabatic decay mechanism of an excited hydrated electron [PDF]
, 2007 We present a kinetic analysis of the non-adiabatic decay mechanism of an excited state hydrated electron to the ground state. The theoretical treatment is based on a quantized, gap dependent golden rule rate constant formula which describes the non ...

Temperature-Dependent Dual Fluorescence from Small Organic Molecules
Organic Materials, 2022 The temperature-dependent dual fluorescence from a single component of small organic molecules (SOMs) is very promising for the ratiometric fluorescence sensing of temperature. However, the SOM-based fluorophores typically only show one fluorescence band.

Hyperridge of triply excited states [PDF]
Physical Review A, 1988 We present a theory for the definition and the reliable calculation of correlated wave functions of a special class of triply excited states and for their rigorous geometrical analysis. This class is named the three-electron ionization ladder (THEIL) and refers to the simultaneous excitation of three electrons in valence states near threshold ...

Some applications of excited-state-excited-state transition densities [PDF]
Physical Review A, 1975 We derive an approximation for transition moments between excited states consistent with the approximations and assumptions normally used to obtain transition moments betwen the ground and excited states in the random-phase approximation and its higher-order approximations. We apply the result to the calculation of the photoionization cross sections of

Excited-state OH Mainline Masers in AU Geminorum and NML Cygni
, 2007 Excited-state OH maser emission has previously been reported in the circumstellar envelopes of only two evolved stars: the Mira star AU Geminorum and the hypergiant NML Cygni.

Entropy, chaos and excited-state quantum phase transitions in the Dicke model [PDF]
, 2016 We study non-equilibrium processes in an isolated quantum system ---the Dicke model--- focusing on the role played by the transition from integrability to chaos and the presence of excited-state quantum phase transitions.

The Journal of Physical Chemistry A, 2023 The modeling and interpretation of vibrational spectra are crucial for studying reaction dynamics using vibrational spectroscopy. Previous theoretical developments have mainly focused on fundamental vibrational transitions. In this study, we present a new method that uses excited state constrained minimized energy surfaces (CMES) to describe ...
