Isotopes and isotopologues, molecules with differing isotopic compositions, have diverse applications in science. They uncover the origins of wine, determine the age of bones and fossils, and serve as essential diagnostic tools in the field of medicine. Their significance extends to astronomy as well, where, for instance, the ratio of carbon-12 (¹²C) to carbon-13 (¹³C) isotopes within an exoplanet's atmosphere provides valuable insights into the exoplanet's orbital distance from its central star.
