The kinetic energy dependence of the reactions of Nb+ (5D) with methane, ethane, and propane have been studied using guided ion beam mass spectrometry. It is found that dehydrogenation is efficient and the dominant process at low energies in all thre

Reactions of Ti+ and V+ with C3H8, CH3CD2CH3, CD3CH2CD3, and C3D8 are studied to characterize the rate-limiting transition states and determine the factors that control the branching between H2 and CH4 elimination. For ground-state Ti+ reacting with

The depletion kinetics of excited-state Cr(a5DJ, a5S2) upon interaction with O2, NO, and N2 have been studied in a discharged flow reactor at He pressures of 0.5 and 0.7 Torr. The interaction with N2 showed no depletion of Cr(a5DJ, a5S2) but an incre

A guided-ion beam mass spectrometer is used to study the reactions FeCH2+ + D2 and Fe+(6D,4F) + CD4, thereby experimentally probing the [FeCH4]+ potential energy surface (PES). The results obtained are compared to recent theoretical results. Experime

The dissociation thermochemistry of tetramethylsilane cation was investigated by two new methods, threshold collision-induced dissociation (CID) and zero-pressure thermal infrared radiation-induced dissociation (ZTRID). For the loss of a methyl group

A guided ion-beam tandem mass spectrometer with a flow tube ion source is used to determine the 0 K bond dissociation energy of Co + -H 2 from ligand exchange of CoCH 4 + with D 2 and from collision-induced dissociation (CID) of CoH 2 + + Xe. Given D

A guided-ion beam mass spectrometer is used to examine the collision-induced dissociation of ground state N 3 + ( 3 Σ − ) from thermal to 20 eV energy with Ne, Ar, Kr, and Xe. The product distribution observed in these systems varies substantially
