Abstract
Laser-induced desorption of neutral fragments from the surface of thin organic corbathiene and polythiophene films is studied by means of ti me-of-flight (TOF) mass-spectrometry. Desorption takes place under las er excitation in the wavelength range corresponding to the pi-absorpti on band of the organic films. The discussed processes of fragmentation and fragment desorption are stimulated via photo-electronic excitatio n of the large organic molecules.
