Laser-induced desorption of molecules from a dielectric surface due to an energy transfer between adsorbed molecules

We have established that an energy transfer occurs between NO and co-adsorbed CO and N 2 molecules following the photoexcitation of (NO) 2 dimers adsorbed on an MgF 2 substrate. The NO is desorbed in the (v equals 1) states. The photoexcitation of (NO) 2 dimers with mixture of CO or N 2 leads to the desorbtion of NO the co-adsorbed species. Using (2 + 1) REMPI we have found that the CO is desorbed in the (v equals 0) with a rotational temperature of 380 +/- 30 K. The desorbed N 2 and CO have the translational energies lower than of NO.
