Symposium in celebration of Prof. Ad van der Avoird's 80th birthday

We're organizing in Nijmegen on Friday 3 Nov 2023 a symposium in celebration of Prof. Ad van der Avoird's 80th birthday. See the symposium website for more information, programme, and registration (free).

Computer codes available

Open source computer code is available through gitlab. This currently contains our code for the computation of the density of states and photo-excitation rate of molecule-molecule collision complexes.
