Carbon dimer: precision measurement delivers new record value

New value deviates significantly from a much-noticed 2019 measurement, but agrees with older quantum chemical calculations

05-Jun-2026 - A team led by Innsbruck physicist Roland Wester has determined a fundamental property of the carbon dimer with unprecedented accuracy in the laboratory. The results provide a high-quality reference value for future calculations of the electronic structure of carbon molecules. Carbon is the basic ...
