Paper Abstract

We have established that an energy transfer occurs between NO and co-adsorbed CO and N2 molecules following the photoexcitation of (NO)2 dimers adsorbed on an MgF2 substrate. The NO is desorbed in the (v equals 1) states. The photoexcitation of (NO)2 dimers with mixture of CO or N2 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 N2 and CO have the translational energies lower than of NO.
