Comparative investigation of infrared multiphoton dissociation of CHF2Cl, C2H4FCl, C3H6FCl, and C4H8FCl molecules

The experimental dependences of the degree of dissociation of CHF₂Cl, C₂H₄FCl, C₃H₆FCl, and C₄H₈FCl molecules on the energy (power) density and laser pulse duration were determined and compared. It was found that C₃H₆FCl and C₄H₈FCl reached a quasicontinuum on absorption of just one photon emitted by a CO₂ laser. The beginning of a continuum was estimated for CHF₂Cl and C₂H₄FCl.
