No Molecule is an Island: Intermolecular Forces Rule! Most chemistry takes place in the liquid phase where many important properties such as vapour pressure, boiling point, surface tension, and viscosity can be explained in terms of the interactions between molecules. Intermolecular interactions are one of the principal forces that govern molecular recognition and influence the structures of proteins, DNA, and solid materials. They also play a significant role in the control of interactions of certain drugs with DNA and the conductive properties of molecular wires (single molecules that can form electrically conducting bridges).How intermolecular interactions affect a liquid's physical and molecular properties is the focus of Dr. Dale Keefe's research. Keefe investigates the microscopic properties of molecules and, in particular, their vibrations.  These interactions are studied using techniques such as infrared and Raman spectroscopy and computer simulations.  This research has the potential to have impact in many areas of chemistry, biochemistry, biology and chemical physics.

没有分子是一个岛：分子间力的规则！大多数化学反应发生在液相中，其中许多重要的性质，例如蒸汽压、沸点、表面张力和粘度，都可以用分子之间的相互作用来解释。分子间相互作用是控制分子识别和影响蛋白质、DNA和固体材料结构的主要力之一。它们还在控制某些药物与DNA的相互作用以及分子线（可以形成导电桥的单分子）的导电特性方面发挥着重要作用。分子间相互作用如何影响液体的物理和分子特性是Dale Keefe博士的研究重点。Keefe研究分子的微观性质，特别是它们的振动。这些相互作用使用红外和拉曼光谱和计算机模拟等技术进行研究。这项研究有可能在化学，生物化学，生物学和化学物理学的许多领域产生影响。
