Torsional Vibrational Modes of Tryptophan Studied by Terahertz Time-Domain Spectroscopy
2004, Biophysical JournalCitation Excerpt :The dynamics of molecular components of proteins involves low-frequency collective modes of particular subunits. Molecules excited up the vibrational ladder can cross transitional energy barriers (Austin et al., 1991; Woolard et al., 2002). The dynamics of the collective modes generally occur via anharmonic interactions with other normal molecular modes, leading to energy exchange.
Modulations of electronic tunneling rates through flexible molecular bridges by a dissipative superexchange mechanism
2004, Chemical PhysicsCitation Excerpt :However, the same change of mechanism is demonstrated and explained also in fully entangled quantum simulations of electronic–nuclear dynamics, for a single-mode bridge. Our conclusions regarding the modulation of the tunneling rate due to energy dissipation in a flexible bridge are in agreement with experimental evidence for the dependence of electronic superexchange rate in donor–bridge–acceptor systems on the molecular bridge configuration, and flexibility [1–15]. However, the present study may have over emphasized the role of energy dissipation, since it was restricted to zero temperature where thermally activated processes and dephasing were excluded.
