In this project in the Experimental Physical Chemistry Program of the Chemistry Division, Professor Baer will design and carry out experiments in the infrared region of the spectrum to measure the rates with which loosely bound clusters of atoms and ions come apart. The ultraviolet region of the spectrum will be used to probe the behavior of more complex organic compounds containing oxygen and nitrogen. The high resolution infrared spectroscopy and dissociation rates of loosely bound ionic clusters will be investigated by IR photodissociation of mass selected cluster beams. The ion lifetimes will be measured in real time. The Rydberg spectroscopy of oxygen and nitrogen containing ring compounds will be investigated by resonance enhanced multiphoton ionization to explore the origin of the spectral sensitivity to a molecule's stereochemistry.

在化学系实验物理化学项目的这个项目中，贝尔教授将在光谱的红外区域设计并进行实验，以测量松散结合的原子和离子簇分开的速率。 光谱的紫外区域将用于探测包含氧和氮的更复杂的有机化合物的行为。 将通过质量选择的簇束的红外光解来研究松散结合的离子簇的高分辨率红外光谱和解离速率。 离子寿命将被实时测量。 将通过共振增强多光子电离来研究含氧和氮环化合物的里德伯光谱，以探索光谱敏感性对分子立体化学的起源。
