A UV-Microwave Optical Double Resonance Study of Transient Molecules

这项实验物理化学的资助是为了支持紫外-微波光学双共振研究项目，并将首先开发一台紫外-微波光学偏振光谱仪，然后用于研究极短寿命(瞬时)分子的动力学和结构。了解这些化学中间体的基本物理性质(偶极矩、键长、电子特征和态分布)对于理解化学反应的速度和路径很重要。将要研究的特定分子包括过渡金属氧化物、稳定的自由基，如FeCo和NiCo，以及甲醛、甲基氮和氢氧化镁的基态和低激发态。对于后者，将研究特定的状态过程，如辐射和非辐射能量分布、解离和异构化。

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.
