Description	Reactions induced by the impact of acetonitrile and deuterated acetonitrile molecular ions on a hydrocarbon-covered stainless steel surface were investigated using a recently constructed tandem mass spectrometer (BESTOF). Mass spectra of product ions formed were recorded for projectile collision energies in the range of about 5-70 eV. Both, simple dissociations of the projectile ion and chemical reactions involving H-atom transfer from the surface material (followed by subsequent dissociation of the protonated projectile ion formed) were observed. In particular, formation of CD2H+ and CD3+ via dissociation of the surface-protonated deuterated acetonitrile ion CD3CNH+ and the collision energy dependence of their relative abundance indicate substantial degree of isomerization of the acetonitrile molecular radical cation CD3CN.+ to the ketenimine ion CD2=C=ND.+.
