Chemical and Isotopic Composition Analysis of Gas Mixtures Using High-Resolution Laser Spectroscopy

The work addresses the issue of precision measurement of the concentration of molecular gas components in the atmosphere and their isotopic composition. The primary focus is investigating the composition of gas mixtures and determining the isotopic ratios of individual gas components using proposed local and remote methods for detecting the content of methane, carbon dioxide, and water vapour molecules based on laser spectroscopy in the infrared range.
