The dissociation products of CF2Cl2 irradiated in the line P20 at 9.17 μm with pulses of fluence as high as 60E4 J*m^-2 depend on the pressure of the gas, giving rise to C2F4 only when the pressure is of the order of 2 mb.At remarkably lower fluence (2E4 J*m^-2) this product appears however in a wide range of pressures. For CF2HCl, C2F4 is the only product that appears at fluences as high as 60E4 J*m^-2).At lower fluences (2.5E4 J*m^-2), less C2F4 is produced and another product, probably a halogenated derivative of butane, is obtained.
