We study how tailoring noncovalent interactions through the regiochemistry of common
donor–acceptor polymers can alter their excited-state electronic properties. Specifically, we …

A new approach is proposed to describe intermediate-to-strong linear vibronic coupling in
an infinite molecular crystal. The Hamiltonian, transformed to the Lang–Firsov …

The peculiar shape of c-polarized absorption spectra of crystalline oligothiophenes is
attributed to the coupling between the intense upper Davydov component originating from …

Charge-modulation spectroscopy was applied to vacuum-sublimed films of pentacene in the
metal–insulator–semiconductor configuration with Parylene-C or cross-linked polymer as …

A quantum-electrodynamic approach is studied as an alternative to the classical description
of polaritons in molecular crystals, with the focus on future interpretation of oligothiophene …

Polariton effects in a model molecular crystal with several molecules in the unit cell are
described within a semiclassical formalism taking complete account of the strong …

A novel approach, recently proposed to describe exciton–phonon coupling in Frenkel states
of an infinite molecular crystal, is generalized to incorporate charge‐transfer (CT) excitons …

An explicit formula expressing the refractive index in terms of exciton energies and oscillator
strengths is used to calculate the absorption spectrum of the crystal at zero and non‐zero …

The difficulties that emerge in modeling the interaction between the Frenkel and CT excitons
in organic molecular systems are reviewed, with special emphasis on vibronic coupling …

The advantages of electroabsorption (EA) spectroscopy are described and an overview of
the theoretical approaches instrumental in the interpretation of EA spectra of organic …
