The Centre for Theoretical and Computational Chemistry (CTCC) is a Norwegian Centre of Excellence (CoE) shared between the Universities of Tromsø and Oslo, established by the Research Council of Norway for a 10-year period in 2007. Led by 10 principal scientists, the CTCC comprises about 60 members, in addition to visiting researchers from all over the world.

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.
