Professor Farley will study the high resolution laser spectroscopy of negative molecular ions. Rare species of ions, normally difficult to produce in sufficient density to study, will be measured using a coaxial ion- and laser-beam spectrometer placed at the center of an optical buildup cavity. Photofragmentation and autodetachment of the negative ions as a function of optical excitation will lead to basic understanding of the electron-nuclear coupling processes in negatively charged molecular species.

法利教授将研究负分子离子的高分辨率激光光谱。 稀有离子通常难以以足够的密度产生以供研究，将使用放置在光学累积腔中心的同轴离子和激光束光谱仪进行测量。 作为光激发函数的负离子的光断裂和自动分离将导致对带负电分子物质中电子-核耦合过程的基本了解。
