研究目的
To review the three most widespread experimental methods for multidimensional vibrational coherence spectroscopy (multi-VCS) and illustrate their application in understanding molecular structural changes and photochemical reactions.
研究成果
Multidimensional vibrational coherence spectroscopy is established as one of the state-of-the-art non-linear spectroscopy techniques for the investigation of ultrafast photoreactivity in molecules. It is a technique of choice for monitoring vibrational dynamics in excited states with unparalleled time resolution.
研究不足
The paper discusses challenges in data interpretation due to the existence of several possible contributions to the observed signals or to optical interferences. It also mentions the difficulty in distinguishing between vibrational signatures specific of each electronic state.
