在他的项目中，米勒将对活性化学中间体进行光谱检测和表征实验，该项目由化学部实验物理化学计划资助。使用的方法是基于激光诱导荧光(LIF)和腔振荡法(CRDS)技术的中分辨率振动分辨光谱和高分辨率旋转分辨光谱。所研究的体系是首席研究员在前一个赠款周期中发现的烷基过氧基。化学反应通常沿着几种可能的反应途径之一进行，从初始反应物到反应产物。反应中间体一般具有不同的短寿命。了解这些反应中间体、它们发生的相对可能性和它们的寿命在预测化学反应的流动中起着重要的作用。选择用于研究的系统对于大气的化学、一些工业过程以及我们对活性分子的一般理解都是重要的。这项研究旨在检测和表征这类中间体。学生和博士后研究助理参与了这项研究。因此，他们获得了重要的知识和技能，为进入科学/技术工作大军做准备。在他的项目中，米勒将对活性化学中间体进行光谱检测和表征实验，该项目由化学部实验物理化学计划资助。使用的方法是基于激光诱导荧光(LIF)和腔振荡法(CRDS)技术的中分辨率振动分辨光谱和高分辨率旋转分辨光谱。所研究的体系是首席研究员在前一个赠款周期中发现的烷基过氧基。化学反应通常沿着几种可能的反应途径之一进行，从初始反应物到反应产物。反应中间体一般具有不同的短寿命。了解这些反应中间体、它们发生的相对可能性和它们的寿命在预测化学反应的流动中起着重要的作用。这项研究旨在检测和表征这类中间体。学生和博士后研究助理参与了这项研究。因此，他们获得了重要的知识和技能，为进入科学/技术工作大军做准备。

In his project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Miller will conduct spectroscopic detection and characterization experiments on reactive chemical intermediates. The methods used are medium resolution, vibronically resolved and high resolution, rotationally resolved spectroscopy, based on laser-induced fluorescence (LIF) and cavity ringdown spectroscopy (CRDS) techniques. The systems under investigation are alkyl peroxy radicals discovered by the principal investigator during the previous grant cycle.Chemical reactions proceed from initial reactants to the reaction products usually along one of several possible reaction pathways. The reaction intermediates are generally characterized by different short lifetimes. Knowledge of these reaction intermediates, the relative likelihood of their occurrence and their lifetimes plays an important role in predicting the flow of chemical reactions. The systems chosen for investigation are important to the chemistry of the atmosphere, some industrial process, and to our general understanding of reactive molecules. This research is designed to detect and characterize such intermediates. Students and postdoctoral research associates participate in this research. They thereby acquire important knowledge and skills in preparation for entry into the scientific/technological workforce.
