Abstract

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