VAMDC is an open, scientific, worldwide e-infrastructure that inter connects databases with data on atoms and molecules. The atomic and molecular data available through our infrastructure describe the microscopic world of atoms, molecules, particles and their interaction: energies, frequencies, radiative transitions and their properties, reaction properties for simple systems.

Our data are used by researchers from other domains; for example:

• in astrophysics in order to understand the chemical composition of a galaxy, of an interstellar cloud, of a planet’s or star’s atmosphere
• in atmospheric physics in order to find the concentration of pollutants of our atmosphere and even for measuring the speed of wind
• in plasma physics
• in biophysics in order to simulate the path of electrons in living tissues for radiotherapy applications
