A time-of-flight (TOF) mass spectrometry gating technique is applied to a study of methanol clusters subjected to ionizations via intense femtosecond laser pulses. The resulting high charged species (C2+, C3+/O4+) acquire large amounts of kinetic ene

Pyridine clusters are subjected to intense femtosecond laser pulses at fluences around 10 15 W cm −2 at 620 nm, which results in multiple ionization and concomitant Coulomb explosion. A combined covariance map is considered which can be viewed as t

Femtosecond pump-probe spectroscopic studies on mixed methanol/water clusters are presented. Two-photon absorption of light was employed to generate methanol molecules in the 3p Rydberg excited state, with transfer to the 3s Rydberg state during the

The studies presented herein elucidate details of the Coulomb explosion event initiated through the interaction of heterocyclic clusters with an intense femtosecond laser beam (⩾1 PW/cm2). Clusters studied include 7-azaindole and pyridine. Covarian

A new method is presented for determining the mass of products resulting from metastable decay in a reflectron time-of-flight mass-spectrometer. The validity of the calculation was confirmed through comparison to experimental values obtained while st

Ultrafast pump−probe spectroscopic studies on the hydrated 7-azaindole monomer are presented. The experiments provide evidence that excited-state proton transfer in the gas-phase hydrated 7-azaindole monomer may be possible, as predicted by theory,

A new concept to study the dynamics of chemical reactions in real time is presented using the phenomenon of Coulomb explosion to arrest and directly interrogate the intermediates in a chemical reaction. This technique is employed to study the tautome
