A chirped pulse microwave spectrometer for studying atmospheric chemistry

点击翻译按钮获取中文摘要

This project aims to construct a microwave spectrometer with a unique molecular source to study atmospheric chemistry. Criegee intermediates formed by the ozonolysis of terpenes are key species in atmospheric chemical processes. Only very recently have small Criegee intermediates been detected by various spectroscopic methods. In this project a purpose-built chirped, pulsed Fourier transform microwave spectrometer will be coupled with a specialised molecular source that will enable their direct observation and characterisation by rotational spectroscopy. This will allow the structure of these molecules to be determined, which will provide insights into their reaction mechanisms.
