In the second part of this review (see preceding article for Part I), desorption‐induced processes by polyatomic projectiles over a broad energy range is described. The nonlinear increase in secondary ion yields as a function of the number of constituent atoms, which is evidence for “collective” effects, is discussed. Effects accompanying ion ejection upon monotornic or polyatomic particle impact, namely secondary electron emission, impact‐induced luminescence (photon emission), and sputtering of clusters (fullerenes in particular) by energetic ions, are intimately related to the mechanisms of desorption, and for that reason are also reviewed. Some of these phenomena, linked to, e.g., methods of ion detection, have (or may have in the future) practical applications in analytical mass spectrometry. In conclusion, selected examples for useful analytical applications of desorption methods like PDMS and FAB mainly in the biochemical field, which may illustrate current and emerging trends and perspectives, are discussed. © 1996 John Wiley & Sons, Inc.
