Trapped ion cyclotron resonance spectroscopy has beer. used for the fist time to study the electron impact dissociation of ions. Fragmentation of CeHsCN+ to produce ChH$ and HCN is observed to occur at low electron energies (3-9 cV). The extent of dissociation is observed to be linear in emission current, rising from a threshold at 3.0 -+ 0.5 eV to a maximum cross section esttmdted to be 6 A* at 7.5 f 0.5 eV. The impIicrttions of these results are discussed.

## Electron impact ionization-collision-induced dissociation (EI-CID) and negative ion chemical ionization-collisioninduced dissociation (NICI-CID) experiments have been performed on the molecular or quasi-molecular ions (M+' or [M -m-) of series of terpenoid alcohols, using a Fourier transform io
