Summary

BOTH THE VIBRATIONAL SUPEREQUILIBRIUM EXCITATION AND THE ROTATIONAL COOLING EFFECT WITH DESORPTION OF CO2 MOLECULES FROM A TITANIUM FOIL SURFACE WERE FOUND BY MEANS OF DIODE LASER SPECTROSCOPY. THE MOLECULE DESORPTION IS PERFORMED IN A THERMOPULSE WAY. THE EVALUATION FOR THE BINDING ENERGY OF MOLECULES WITH THE SURFACE GIVES 0.22 ELECTRONVOLTS. FOR THE TEMPERATURE VARIATION OF THE SURFACE IN THE RANGE OF 120-180 K, THE ROTATIONAL AND VIBRATIONAL TEMPERATURES OF DESORBING MOLECULES ARE 110 K, MORE OR LESS 10 K AND 220 K, MORE OR LESS 20 K.
