Atoms, 2023 The exponentially correlated Hylleraas–configuration interaction method (E-Hy-CI) is a generalization of the Hylleraas–configuration interaction method (Hy-CI) in which the single rij of an Hy-CI wave function is generalized to a form of the generic type

Biexciton oscillator strength [PDF]
Physical Review B, 2009 Our goal is to provide a physical understanding of the elementary coupling between photon and biexciton and to derive the physical characteristics of the biexciton oscillator strength, following the procedure we used for trion. Instead of the more standard two-photon absorption, this work concentrates on molecular biexciton created by photon absorption

Experimental Mo
Journal of Physics B: Atomic, Molecular and Optical Physics, 2001 Experimental branching fractions (BFs) of Mo (II,) ranging in wavelength from 1970 to 4370 Angstrom, have been measured from intensity calibrated spectra recorded with the Lund UV Fourier transform spectrometer (FTS). Radiative lifetimes for 10 levels have been measured using the method of laser-induced fluorescence (LIF).

Where Is the Electronic Oscillator Strength? Mapping Oscillator Strength across Molecular Absorption Spectra [PDF]
The Journal of Physical Chemistry A, 2016 The effectiveness of solar energy capture and conversion materials derives from their ability to absorb light and to transform the excitation energy into energy stored in free carriers or chemical bonds. The Thomas-Reiche-Kuhn (TRK) sum rule mandates that the integrated (electronic) oscillator strength of an absorber equals the total number of ...

Computational Comparison of CPDT to other Conjugated Linkers in Triarylamine-based Organic Dyes
CHIMIA, 2013 The use of the cyclopentadithiophene (cpdt) fragment to chemically link electron donor and acceptor groups has become a rather common procedure to design new organic dyes with enhanced light harvesting properties.
