The energetics, interfacial properties, instabilities, and fragmentation patterns of electrosprays made from formamide salt solutions are investigated in a mass spectrometric vacuum electrospray experiment and using molecular dynamics (MD) simulation

Theoretical and experimental methods are applied to the study of the reaction dynamics in hyperthermal collisions of O+ (4S3/2) with methane. Measurements of the absolute reaction cross sections for the interaction of O+ with CD4 and CH4 were obtaine

Theoretical and experimental studies are performed to elucidate the low energy charge-transfer dynamics of the reaction, O+(4S)+C2H2(X 1Σg+)→O+C2H2+. In particular, the role of the low-frequency acetylene bending modes (612 and 730 cm−1) in prom

The first measurement of ion photodissociation product recoil velocity and angular anisotropy in an octopole ion guide are presented. The experimental and numerical procedures required to obtain photofragment ion translational energy and angular dist

We present low energy collision-induced dissociation (CID) and visible photodissociation (PD) data of jet-cooled (N2O,H2O/D2O)+ cluster ions. The same three fragment ions are observed in both CID and PD, namely, H2O+/D2O+, N2O+, and N2OH+/N2OD+. The

We present the angular and kinetic energy distributions for the products of the proton transfer reaction O− + HF → OH + F− at center-of-mass collision energies of 45.0 and 55.8 kJ mol−l (0.47 and 0.58 eV, respectively). At both collision ener

We present the angular and kinetic energy distributions for the products of the proton transfer reaction O−+HF→OH+F− at a center of mass collision energy of 40.5 kJ mol−1 (0.42 eV). The angular distribution shows clear forward–backward symm

Reactive and nonreactive collisions of O− with NH3 are studied at relative collision energies of 0.65 and 1.24 eV. We observed a significant contribution to the collision dynamics from nonreactive encounters between the reagents. In addition to ela

We present a study of reactive and nonreactive collisions between O− and H2O over the collision energy range from 0.67 to 1.07 eV. Kinetic energy analysis of the O− scattered nonreactively from H2O shows two components: The first arises from dire

We have measured the infrared photodissociation spectra of argon clusters containing SiF4, as a function of the cluster size n (for n≤ 103) using molecular beam laser spectroscopy. The clusters were produced by both the conventional seeded expansio
