Toward the Understanding of Intramolecular Energy Transfer
Intramolecular electronic energy transfer is intimately related to vibrational energy transfer in many ways, both in the systems studied and in the computational methods employed. Due to the rapid rise of interest in molecular computing, understanding the more complicated electron transfer problems …

Ultrafast Vibrational Dynamics of Water and Confined Water in Reverse Micelles
A fast vibrational energy transfer across the surfactant layer of AOT reverse micelles has been measured in small AOT reverse micelles (AOT/water/CCl 4). Most of the vibrational energy from nanodroplet water is transferred to the AOT head group and then out to the CCl4 within 10 picoseconds. The …
