CEQPAS – Centennial of Quantum Theory: Progress in Atomic and Molecular Structure” will be held in Belgrade, Serbia from 3–5 November 2025. Organized by the University of Belgrade – Institute of Chemistry, Technology and Metallurgy, University of Belgrade – Institute of Physics, and the MOLESs consortium, this three-day symposium will be part of the International Year of Quantum regional activities. It will welcome up to 40 participants, with priority for researchers from Central and Eastern Europe and a special focus on early-career scientists. It will feature oral presentations by all delegates.

The program will be structured into five interlinked sessions: 1. Atomic and molecular spectroscopy and its applications to atmospheric sciences and astronomy. 2. Collisions and their applications in plasma physics. 3. Studies in chemical physics and physical chemistry. 4. The use of artificial intelligence and machine learning for atomic and molecular data analysis and generation. 5. The application of quantum science to our wider understanding of phenomena, including radiation sciences.

There is no registration fee; participants are responsible for their travel and accommodation. Further details will be available on the CEQPAS website.
