Abstract

Vibrational super-equilibrium excitation and the simultaneous effect of rotational cooling have been measured for CO₂ molecule desorption from a titanium foil surface using diode-laser spectroscopy. CO₂ molecules were desorbed when the foil was heated by a current impulse. CO₂ molecules binding energy with the titanium surface is equal to approximately 0.22 eV. The vibrational and rotational temperatures are equal to 100 +/- 10 K and 220 +/- 20 K accordingly, for the surface temperature range of 120 K - 180 K.
