We review a theory for coupled many-nonlinear oscillator systems that describes quantum
ergodicity and energy flow in molecules. The theory exploits the isomorphism between …

Energy transport in molecules is essential for many areas of science and technology. Strong
covalent bonds of a molecular backbone can facilitate the involvement of the molecule's …

We use femtosecond stimulated Raman spectroscopy (FSRS) to illuminate the
choreography of intermolecular excited-state proton transfer (ESPT) of photoacid pyranine …

Energy transport during chemical reactions or following photoexcitation in systems of
biological molecules is mediated by numerous interfaces that separate chemical groups and …

Recent progress in transient infrared spectroscopy has made it possible to monitor the
transient flow of vibrational energy along a peptide helix [V. Botan et al, Proc. Natl. Acad. Sci …

Vibrational energy transfer (VET) is believed to play an important role in protein function.
Theoretical studies predict highly directional, anisotropic VET in proteins. Distinct energy …

The two-dimensional infrared spectrum of an octameric helical peptide in chloroform was
measured as a function of temperature. Isotope labeling of the carbonyl group of one of the …

Vibrational energy transport in a short 310-helical peptide is studied by time-resolved
femtosecond infrared spectroscopy. The C− D vibrations of decadeuterated leucine …

Vibrational energy relaxation and transport in a molecule that is far from thermal equilibrium
can affect its chemical reactivity. Understanding the energy transport dynamics in such …

Vibrational energy transfer (VET) is essential for protein function. It is responsible for efficient
energy dissipation in reaction sites, and has been linked to pathways of allosteric …
