The infrared multiphoton decomposition of diethyl ether (DEE) has been investigated by the cross laser-molecular beam technique.The center-of-mass product translation energy distributions (P(E')) were measured for the two dissociation channels: (1) DEE -> C2H5O + C2H5 and (2) DEE -> C2H5OH + C2H4.The shape of the P(E') measured for radical channel 1 is in agreement with the predictions of statistical unimolecular rate theory.The translational energy released in concerted reaction 2 peaks at 24 kcal/mol; this exceedingly high translational energy release with a relatively narrow distribution results from the recoil of the products from each other down the exit barrier.Applying statistical unimolecular rate theory, we estimate the average energy levels from which DEE dissociates to products using the measured P(E') for radical channel 1.

The rate constants for the gas-phase reactions between methylethylether and hydroxyl radicals (OH) and methylethylether and chlorine atoms (Cl) have been determined over the temperature range 274-345 K using a relative rate technique. In this range the rate constants vary little with temperature and average values of kMEE+OH = (6.60-2.62+3.88) × 10-12 cm3 molecule-1 s-1 and kMEE+Cl = (34.9 ± 6.7) × 10-11 cm3 molecule-1 s-1 were obtained. The atmospheric lifetimes of methylethylether have been estimated with respect to removal by OH radicals and Cl atoms to be ca. 2 days and ca. 30-40 days, respectively.
