Rotational Spectrum

Rotational spectroscopy analyzes the rotational energy levels of molecules to determine their three-dimensional structures, serving as a highly accurate method for gas-phase molecular characterization. Current research focuses on improving the analysis of complex mixtures using machine learning techniques to identify individual components and addressing the challenge of non-unique spectral fingerprints by developing algorithms to distinguish structurally different molecules with similar spectra. These advancements are significantly impacting fields ranging from materials science and astrochemistry to planetary science, enabling more precise identification and characterization of molecules in diverse environments.
