This grant in experimental physical chemistry is to support a research project in ultraviolet-microwave optical double resonance and a uv-microwave optical polarization spectrometer will be first developed and then used to study the dynamics and structures of very short lived (transient) molecules. Knowledge of the fundamental physical properties (dipole moments, bond lengths, electronic character and state distributions) of such chemical intermediates are important in understanding the rates and paths of chemical reactions. The specific molecules that will be studied include transition metal oxides, stable radicals such as FeCO and NiCO and ground and low lying excited states of formaldehyde, methylnitrene and MgOH. For the latter, state specific processes, such as radiative and nonradiative energy distribution, dissociation, and isomerization will be investigated.

实验物理化学中的这种赠款是为了支持紫外线光学双共振的研究项目，将首先开发出UV-Microwave光学极化光谱仪，然后用于研究非常短的（瞬态）分子的动力学和结构。 这种化学中间体的基本物理特性（偶极矩，键长，电子特征和状态分布）的知识对于理解化学反应的速率和路径很重要。 将要研究的特定分子包括过渡金属氧化物，稳定的自由基，例如Feco和Nico，地面以及甲醛，甲基硝基和MGOH的稳定的激发态。 对于后者，将研究诸如辐射和非辐射能分布，解离和异构化等状态特定过程。
