The dynamics of the SiF4 - sensitized processes initiated by a pulsed CO2 laser

Abstract A model enabling the examination of the dynamics of the SiF 4 - sensitized processes initiated by a pulsed CO 2 laser is outlined, taking into account three effects : energy absorption, energeticity of chemical reactions and expansion of hot gas created upon interaction of molecules with the infrared photon field. This approach was used to elucidate some aspects regarding the decomposition of PH 3 and GeH 4 .
