Abstract
Laser induced thermal desorption has been tested as a method of modula ting the coverage of CO in planned time-resolved FTIR experiments. CO can be completely desorbed in similar to 10 ns from Pt(100) without da maging the surface or indeed causing the (1 X 1) to hex transition, ev en though peak temperatures of similar to 1600 K are reached. In therm al transients in which no desorption occurs, conversion of linearly bo nded to bridge bonded CO is observed, suggesting that the species are not in equilibrium at room temperature.
