Spectroscopic and thermodynamic studies on temperature-controlled biomolecules with water

我们采用红外耗尽光谱法对从低温到高温加热的气相中的分子团簇进行研究。基于实验和理论结果，我们得到了水合团簇结构涨落的信息。其中一个簇显示了侧链构象的重折叠和结构波动。这些动力学过程之间存在相关性。熵效应在本研究所观察到的现象中起着重要的作用。

We applied infrared depletion spectroscopy for molecular clusters in the gas phase which was heated up from low to high temperature. Based on experimental and theoretical results, we got information on structural fluctuations of the hydrated clusters. One of these clusters shows the re-folding of side chain conformations and the structural fluctuations. There is a correlation between these dynamical processes. The entropic effect play an important role in the phenomena observed in this study.
