The aim of this thesis is to study pollutants that are emitted from combustion systems using Terahertz time domain spectroscopy (THz-TDS). In particular, this thesis will focus on Nitric Oxide (NO), which is present in flue gases and contributes to air pollution. It is also interesting from a Physics perspective because it contains an unpaired electron in the valence shell, which leads to a complicated energy level structure, and interesting Physics.
In this thesis, we aim to answer the question: “what is the detection limit of NO, using THz-TDS, and is it suitable for industrial emissions monitoring?” It is therefore necessary to look at detection limits, which in turn requires conducting THz spectroscopy at different gas pressures. ...
