Multiple stage MS(2) and MS(3) mass spectrometric experiments, performed using a pentaquadrupole instrument, are employed to explore the gas-phase ion-molecule chemistry of several nitrilium [R-C≡N(+)-H (1), R-C≡N(+)-CH3 (2), and H-C≡N(+)-C2H5 (3)] as well as immonium ions RR(1)C=N(+)R(2)R(3) (4) wi
