Isotopically selective dissociation of CH3SiF3 and C6H5SiF3 molecules by CO2 laser pulses

An experimental investigation was made of the spectral dependences of the isotopic selectivity and of the dissociation yield of CH₃SiF₃ and C₆H₅SiF₃ molecules interacting with CO₂ laser pulses. The results indicated that collisional activation of the molecules played an important part.
