High-resolution spectroscopy is a research area that involves the study of the precise measurement and analysis of the spectral lines of atoms, molecules, and other materials. It typically involves the use of advanced spectroscopic techniques and instrumentation to achieve high levels of resolution and accuracy in measuring the energy levels and transitions of molecules and atoms. This field is important in many scientific disciplines, including chemistry, physics, and astronomy, as it provides detailed information about the structure, dynamics, and interactions of molecules and atoms. High-resolution spectroscopy is used in a wide range of applications, such as in the study of chemical reactions, the identification of compounds, and the determination of the composition of celestial bodies.
