Study of kinetics of dissociative surface ionization of polyatomic molecules

With the high-vacuum mass spectrometric set up having a “black” chamber which all the walls are cooled with liquid nitrogen, adsorption and surface ionization of procaine, imipramine, amitriptyline and tetraethylammonium chloride on the surface of oxidized tungsten have been studied by the VMM and FMM methods. and have been defined for (CH3)2NCH2 and (C2H5)2NCH2, which coincide with the previous results. For the first time and have been defined for reactions of dissociation of molecules adsorbed in (C-C)β bond.
