SiF4 IR Photodissociation: Gas phase reactions of SiF3 with CH4

Mostrar todas las versiones(2)

The infrared multiphoton dissociation (IRMPD) of SiF4 in the presence of CH4 has been studied using a tunable CO2 TEA laser. The siliconated reaction products have been identified. A kinetic scheme has been proposed to explain the experimental results. The reaction rate constant of the trifluorosily...
