The optical properties at 546 nm of three vitrinites (daf carbon contents 82.5, 88.0 and 93.1%) have been examined after pre-oxidation for 14 days at 105°C and carbonization at intervals of 50°C within the temperature range 300-800°C. In general, pre-oxidation prior to carbonization produces only r
