The European Congress on Molecular Spectroscopy (EUCMOS) is held every two years. The first Congress in this series was held in Basel (Switzerland) in 1951. It focuses on all aspects of spectroscopic methods and techniques (including applications), as well as computational and theoretical approaches for the investigation of structure, dynamics, and properties of molecular systems.
This Congress covers various scientific topics including vibrational, electronic and rotational spectroscopies, spectroscopy of surfaces and interfaces, spectroscopy of biological molecules, computational methods in spectroscopy, applied spectroscopies (archaeology, geology, mineralogy, arts, environmental analysis, food analysis, and processing), new materials, and  time-resolved spectroscopy.
