| Abstract | Carbon tetrachloride was subjected to transient laser flash photolysis in the presence or absence of oxygen, transient absorption spectra were observed and analyzed. The experiment indicates that a series of micro-reactions occurred under 248 nm laser by a single photon absorption of CCl4, including the dissociation of the solvent and the formation of sophisticated substances - {CCl4 - Cl} sigma charge transfer complex, (CCl3+ ... Cl-) ion pair and CCl3O2. These absorptions decay according to the first order kinetics, and the decay rate constants of {CCl4 - Cl} sigma charge transfer complex were obtained to be 3.38 x 10(6) s(-1) and 3. 65 x 10(6) s(-1) in the presence and absence of oxygen, respectively, and its production has nothing to do with the oxygen. The decay rate constants of (CCl3+ (...) Cl-) were also gained to be 3.73 x 10(7) s(-1) and 3.02 x 10(7) s(-1) in the presence and absent of oxygen, respectively. However, CCl3O2 exists only in the presence of oxygen with a decay rate constant of 2.32 x 10(4) s(-1). |
