Summary
In this review, we present key theoretical concepts and recent experimental strategies using femtosecond stimulated Raman spectroscopy (FSRS) to map the structural dynamics of proteins, highlighting the flexible chromophores on ultrafast timescales.
Usefulness & Problems
Why this is useful
FSRS is presented as an experimental strategy for mapping protein structural dynamics by following vibrational motions of chromophores on ultrafast timescales. The review also describes its use for capturing excited-state structural snapshots in time and/or frequency domains.; mapping structural dynamics of proteins; tracking chromophore vibrational motions on ultrafast timescales; capturing excited-state structural snapshots
