t is indeed a pleasure and an honour to contribute to this special issue of ChemPhysChem on atmospheric chemistry. It is especially appropriate that it is dedicated to Professors Georges Le Bras, Robert Lesclaux and Philippe Mirabel, three distinguished scientists in the field of physical chemistry who have made and continue to make major contributions to our understanding of fundamental chemical processes applied to atmospheric chemistry. The personal friendship, stimulating professional interaction, willingness and disposition provided by Prof. G. Le Bras will be always appreciated by S.I.L. 2 Abstract The relative rate technique has been used to determine the rate constants of the reactions of OH radicals with CF3CCl=CCl2 (k1), CF3CCl=CClCF3 (k2) and CF3CF=CFCF3 (k3). Experiments were carried out at (298±2) K and atmospheric pressure using ultrapure nitrogen as gas bath. The decay rates of the organic species were measured relative to those of ethane, methanol, aceton
