Frequency characteristics of isotopically selective dissociation of BCl3 in a strong infrared CO2 laser field

The maximum of the dissociation probability of the ¹¹BCl₃ molecule was found to be shifted by 17 cm^–1 in the direction of longer wavelengths, relative to the maximum of the profile of linear absorption, as the result of the ν = 0→ν = 1 transition. An investigation was made of the frequency dependence of the selectivity of the dissociation of the ¹⁰BCl₃ and ¹¹BCl₃ molecules.
