Surface Induced Dissociations of Protonated Ethanol Monomer, Dimer and Trimer Ions: Trimer Break-down Graph from the Collision Energy Dependence of Projectile Fragmentation.

Popis výsledku v původním jazyce

Surface induced dissociation of the protonated ethanol molecular ion, protonated ethanol dimer, and protonated ethanol trimer on a stainless steel surface covered by hydrocarbons was investigated over the incident ion energy range 10-80 eV. Mass spectraof the product ions were recorded and from them the dependencies of the relative abundance of the product ions on the collision energy (CERMS, collision energy resolved mass spectra) were obtained. The dissociation kinetics follows the unimolecular decomposition model of a surface-excited polyatomic projectile behaving as a statistical ensemble. The CERMS curves of the three projectiles, normalized to the same number of internal degrees of freedom, fit each other over the respective energy regions, andmatched together provide information on the break-down pattern of the surface-excited protonated ethanol trimer over a wide energy range. This clearly shows that surface collisions can be used to impart in a defined manner.
