Collision-Induced and Surface-Induced Dissociation (CID and SID) of Ions
An important mass spectrometric technique for dissociating ions is to collide them with inert gases (CID) or with a surface (SID). These experiments provide information concerning the ion's structure, energetics, dynamics, and kinetics. These experiments may be simulated by classical trajectories. A variety of systems have been studied, including peptide ion CID and SID and the collisions of Cr(CO)6+ with the soft alky thiolate self-assembled monolayer (SAM) and diamond surfaces.
