Vibrational excitation and rotational cooling of CO2 molecules desorbed from titanium surface

摘要

Vibrational super-equilibrium excitation and the simultaneous effect of rotational cooling have been measured for CO$-2$/ molecule desorption from titanium foil surface by methods of diode-laser spectroscopy. CO$-2$/ molecules were desorbed when foil was heated up by current impulse. CO$-2$/ molecules binding energy with a titanium surface is approximately equal to 0.22 eV. The vibrational and rotational temperatures are equal to 100 $POM 10 K and 220 $POM 20 K accordingly, for the surface temperature range 120 K - 180 K.
