The passage of CF{sub 3}I molecules excited by high-intensity IR laser radiation to high vibrational states (with energy E{sub v} {>=} 0.3-1.5 eV) and unexcited molecules in a pulsed beam through a converging truncated hollow metal cone cooled to T{sub s} {approx} 80-85 K and mounted at an angle to the beam axis is studied. It is found that the excited molecules pass much more readily through the cone than the unexcited (vibrationally cold) molecules. This opens the possibility for studying the processes of energy transfer and redistribution over a cold surface covered by molecular (cluster) layers, and for separating excited and unexcited molecules in a beam.
