Experimental and theoretical study of temperature dependent exciton delocalization and relaxation in anthracene thin films
(Georgia Institute of Technology, 2008-02)
The spectroscopy of solid anthracene is examined both experimentally and theoretically. To avoid experimental complications such as self-absorption and polariton effects, ultrathin polycrystalline films deposited on ...
Solvent effects on the vibronic one-photon absorption profiles of dioxaborine heterocycles
(Georgia Institute of Technology, 2005-11)
The vibronic profiles of one-photon absorption spectra of dioxaborine heterocycles in gas phase and solution have been calculated at the Hartree-Fock and density-functional-theory levels. The polarizable continuum model ...
Structure-property relationships for three-photon absorption in stilbene-based dipolar and quadrupolar chromophores
(Georgia Institute of Technology, 2006-07)
Based on essential-state models for three-photon absorption (3PA), we have investigated the structure-property relationships for stilbene-based dipolar and quadrupolar chromophores. The emphasis lies on the evolution of ...
Effective conjugation and Raman intensities in oligo(para-phenylene)s: A microscopic view from first-principles calculations
(Georgia Institute of Technology, 2005-03)
Electron-phonon coupling in oligo(para-phenylene)s is addressed in terms of the off-resonance Raman intensities of two distinct modes at 1220 and 1280 cm−1. On the basis of Albrecht’s theory, vibrational coupling and Raman ...
