Abstract: | ![]() The decomposition rate of the chemically activated ethylmethylether produced from dimethyl ether-oxygen-diazomethane photolysis at 3660Å have been measured to be 2~5×106 sec?1. By comparing the pressure dependent variation of rate constants with the RRKM calculation results, the strong collision behavior of dimethylether and the gaussian energy distribution of singlet methylene are determined. |
