Suspended trapping is used to eject electrons in negative-ion Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometric experiments. In contrast to electron ejection by resonant excitation of the trapping motion, suspended trapping involves allowing the electrons to escape along the z-ax

Two-dimensional Fourier transform (2D FT) spectroscopy is applied to ion cyclotron resonance (ICR) to obtain direct evidence for mass transfer due to ion-molecule collisions. The 2D FI ICR experiment, which is closely analogous to 2D exchange NMR spectroscopy (NOESY), yields similar information to t
The experimental Fourier transform ion cyclotron resonance (FT/ICR) frequency range has been extended to 107 MHz. We report the observation of FT/ICR signals from electron-ionized species of mass-to-charge ratio 8, 7, 6, 5, 4, 3, 2, and 1 ΞΌ per elementary charge. We show that moderately high charge
