✦ Synopsis

The laser photolysis-resonance fluorescence technique has been used to determine the absolute rate coefficient for the Cl atom reaction with a series of ethers, at room temperature (298 Ϯ 2) K and in the pressure range 15-60 Torr. The rate coefficients obtained (in units of cm 3 molecule Ϫ1 s Ϫ1 ) are dimethyl ether (1.3 Ϯ 0.2) ϫ 10 Ϫ10 , diethyl ether (2.5 Ϯ 0.3) ϫ 10 Ϫ10 , di-n-propyl ether (3.6 Ϯ 0.4) ϫ 10 Ϫ10 , di-n-butyl ether (4.5 Ϯ 0.5) ϫ 10 Ϫ10 , diisopropyl ether (1.6 Ϯ 0.2) ϫ 10 Ϫ10 , methyl tert-butyl ether (1.4 Ϯ 0.2) ϫ 10 Ϫ10 , and ethyl tertbutyl ether (1.5 Ϯ 0.2) ϫ 10 Ϫ10 . The results are discussed in terms of structure-reactivity relationship.
