Kinetics of Surface Reactions Studied by Laser Desorption with FTMS detection

Kinetics of Surface Reactions Studied by Laser Desorption with FTMS detection

The mechanism of laser induced desorption has been investigated by comparing the wavelength and pulse energy dependence of laser desorption from thermally thin metal films of a variety of thicknesses. We are able to distinguish thermal versus non-thermal laser desorption mechanisms. Laser desorption...
