碩士 === 國立交通大學 === 應用化學系 === 87 === We use a new technuque(laser photolysis/time-resolved Fourier transform absorption spectroscopy) to do the kinetic study of Cl + CH4 reaction. We observe the products of HCl , CH3Cl and CH4 in excited states(CH4*). In the previous reports of this reaction,no one observe this products of CH4*. In our experiments,we get the formation rate coefficient of CH4* :1.07 × 10-13 cm3 molecules-1 s-1 ;the quenching rate coefficient of Cl2 : 4.36 × 10-15 cm3 molecules s-1 ;the quenching rate coefficient of Ar:2.20 × 10-15 cm3 molecules s-1 ;the quenching rate coefficient of O2 :1.79 × 10-14 cm3 molecules s-1
