Vibrational Dynamics in Disordered Molecular Crystals by Picosecond Coherent Raman and Photon Echo Spectroscopies (Exciton, Low Temperature)
Abstract
dc:descriptionAn understanding of vibrational dynamics in complex molecules is a fundamental problem in chemical physics and is important for discerning how vibrational relaxation effects actual chemical reaction rates. The natural states of a pure crystal, however, are delocalized excitons and are described by the language of solid state physics. In this thesis the important processes involved in vibrational exciton (vibron) dynamics are differentiated by investigating vibron relaxation in isotopically and chemically disordered crystals at low temperature by picosecond time-delayed Coherent Anti-Stokes Raman Scattering (psCARS) and photon echo spectroscopy (PE).
