Ro-Vibrational Collisional Excitation
Database and Utilities

This is a new version of the BASECOL website. Should you encounter any problem or if you have a suggestion please contact the persons in the contact section by email.

BASECOL is part of the "Virtual Atomic and Molecular Data Centre" (VAMDC). From the VAMDC portal, you can retrieve the data in XSAMS output, download the data files and read them with the SPECTCOL tool. This tool allows you to combine BASECOL data and spectroscopic data.
This database, called BASECOL is devoted to collisional ro-vibrational excitation of molecules by colliders such as atom, ion, molecule or electron. It is supervised by an international working group of molecular physicists and astrophysicists involved in the calculations and use of ro-vibrational cross-sections, in order to ensure the continuity and the quality of the database.
