This project aims to understand how peroxyl radical reactions modulate the composition of air. The gas-phase chemical reactions of organic peroxyl radicals contribute to air quality in clean and polluted environments. However, experimental observations of these reaction intermediates and the complex mechanisms governing their formation and fate are limited. This project will use mass spectrometry and laser-based methods to interrogate the chemical and photochemical reactions of peroxyl radicals in the gas phase. This project expects to understand the composition and dynamics of the troposphere and inform strategies to improve air quality.

这个项目的目的是了解过氧基反应如何调节空气的组成。有机过氧基的气相化学反应有助于清洁和污染环境中的空气质量。然而，对这些反应中间体及其形成和命运的复杂机制的实验观察是有限的。该项目将使用质谱仪和基于激光的方法来询问气相中过氧基的化学和光化学反应。该项目期望了解对流层的组成和动态，并为改善空气质量的战略提供信息。
