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.

该项目旨在了解过氧根部反应如何调节空气的组成。有机过氧自由基的气相化学反应在干净和污染的环境中有助于空气质量。然而，对这些反应中间体的实验观察以及控制其形成和命运的复杂机制受到限制。该项目将使用质谱和基于激光的方法来询问气相中过氧自由基的化学和光化学反应。该项目希望了解对流层的组成和动态，并为提高空气质量的策略提供信息。
