The Centre for Theoretical and Computational Chemistry (CTCC) is a Centre of Excellence established by the Research Council of Norway in 2007. Having successfully completed its ten-year research programme in 2017, the CTCC is no longer operational.

The CTCC was shared equally between its home institution UiT – The Arctic University of Norway and the University of Oslo. With a total of 150 members, the CTCC was a vibrant and productive research institution, with nearly 800 scientific publications and more than 13000 citations after ten years of operation. Many of its activities are continued at the Hylleraas Centre for Quantum Molecular Sciences, established in 2017. The CTCC web pages are no longer maintained; for more information about the CTCC, see the final report.

Internal pages


The research carried out by the CTCC covers a broad range of themes, with equal emphasis on theory and application projects. Quantum-chemistry methods development uses a broad range of techniques, including linear-scaling and periodic-boundary-condition methods, multiwavelet basis functions, and subsystem optimization. Application projects cover transition-metal chemistry, homogeneous and heterogeneous catalysis, bioinorganic chemistry, photochemistry, gas-phase chemistry, and reaction dynamics. Several projects are closely coupled with ongoing experimental work at the two universities.

Visit CTCC?

CTCC had a generous visitor program, which is no longer operational. Besides appointing PhD students and postdocs, the CTCC also hosted visiting students and scientists for varying periods.
