We use theory to determine the relative rates of 4-, 5- and 6-membered ring H-transfers in closed shell cations, a comparison not possible experimentally due to interference from competing processes. H-transfers of increasing ring size were character

The reactions leading to dissociation of the metastable enol isomers of 2-butanone have a puzzling feature: why does CH3C( OH+)CH2C H2 (2) isomerize to the less stable 2-butanone cation (3) and dissociate to the exclusion of conversion to CH2 C(OH+ )

Previous work demonstrates that rates of H . losses generally increase much less rapidly with increasing internal energy than do those of losses of polyatomic fragments. To determine whether this is also the case for the losses of other atoms, the de

A long-standing mystery in gas phase ion chemistry is: why are smaller fragments preferentially lost at low energies and larger fragments at higher energies in competing α-cleavages? This is addressed here by studies of dissociations of ethanol, 2-p

Concentrations of Mn, Ni, Cu, Zn and Pb in natural waters were measured by inductively coupled plasma mass spectrometry (ICP-MS) with on-line preconcentration using Toyopearl TSK-immobilized 8-hydroxyquinoline resin columns and ultrasonic nebulizatio

AM1 semiempirical molecular orbital calculations are reported for 20 ion-neutral complexes, including hydrogen-bonded complexes, presumably involved in the gas-phase unimolecular decomposition of simple organic radical cations. The systems investigat

The effects of the size of the ionic and neutral partners on ion-neutral complex-mediated alkane eliminations from ionized aliphatic ethers were determined by obtaining metastable decomposition spectra and photoionization ionization efficiency curves
