The past decade has seen rapid advances in our understanding of how coherent and
vibronic phenomena in biological photosynthetic systems aid in the efficient transport of …

Femtosecond stimulated Raman spectroscopy (FSRS) is an ultrafast nonlinear optical
technique that provides vibrational structural information with high temporal (sub‐50 fs) …

We report the first nonadiabatic molecular dynamics study based on the exact factorization
of the electron–nuclear wave function. Our approach (a coupled-trajectory mixed quantum …

Exciton delocalization plays a prominent role in the photophysics of molecular aggregates,
ultimately governing their particular function or application. Deoxyribonucleic acid (DNA) is a …

Femtosecond laser pulses readily produce coherent quantum beats in transient–absorption
spectra. These oscillatory signals often arise from molecular vibrations and therefore may …

Chemistry studies the composition, structure, properties, and transformation of matter. A
mechanistic understanding of the pertinent processes is required to translate fundamental …

Broadband optical pump and compressed white light continuum probe were used to
measure the transient excited-state absorption, ground-state bleach, and stimulated …

Photosynthetic organisms use light-harvesting complexes to increase the spectrum of light
that they absorb from solar photons. Recent ultrafast spectroscopic studies have revealed …

The structure–function relationships of biomolecules have captured the interest and
imagination of the scientific community and general public since the field of structural …

Conical intersections are molecular configurations at which adiabatic potential-energy
surfaces touch. They are predicted to be ubiquitous, yet condensed-phase experiments …
