Kinetic Study of the Reaction between CN and NH Using Laser Photolysis—Laser Induced Fluorescence Technique

碩士 === 國立交通大學 === 應用化學系碩博士班 === 99 === The kinetics of the CN + NH → NCN + H reaction has been studied at 298 K in 270 to 470 torr of He and in 210 to 420 torr of N2 by means of the laser photolysis / laser-induced fluorescence technique coupled with computer simulations. By simulating the observe...
