| 英文摘要 | the photolysis rate of cloocl is crucial in the catalytic destruction of polar stratospheric ozone. in this work, we determined the photodissociation cross section of cloocl at 330 nm with a molecular beam and with mass-resolved detection. the photodissociation cross section is the product of the absorption cross section and the dissociation quantum yield. we formed an effusive molecular beam of cloocl at a nozzle temperature of 200 or 250 k and determined its photodissociation probability by measuring the decrease of the cloocl intensity upon laser irradiation. by comparing with a reference molecule (cl-2), of which the absorption cross section and dissociation quantum yield are well-known, we determined the absolute photodissociation cross section of cloocl at 330 nm to be (2.31 +/- 0.11) x 10(-19) cm(2) at 200 k and (2.47 +/- 0.12) x 10(-19) cm(2) at 250 k. impurity interference has been a well-recognized problem in conventional spectroscopic studies of cloocl; our mass-resolved measurement directly overcomes such a problem. this measurement of the cloocl photolysis cross section at 330 nm is particularly useful in constraining its atmospheric photolysis rate, which in the polar stratosphere peaks near this wavelength. |
