Abstract
Recent studies on laser induced gas-surface interactions with electronic excitation are briefly reviewed. These studies were carried out on the well-defined clean surfaces in ultra-high vacuum systems, and the main tool was a time of flight mass spectrometer. Two studies were reviewed in greater detail, i. e., the systems of CH2I2 on Al2O3 and Ag, and CH3Cl on Ni (111). The former study revealed the characteristic electronic, thermal, and “explosive” desorption effects. The latter showed both direct photolysis and electron-transfer mediated fragmentation of the adsorbate on the metal surface.
