Direct evidence is reported of the connectiveness of charged clusters with highly charged species (N4+, N3+, and N2+) produced upon the interaction of molecular ammonia clusters with an intense femtosecond laser beam (∼1015 W/cm2 at 120 fs). The va

Recent femtosecond pump–probe experiments have suggested that a stepwise dissociative mechanism is operative for acetone excited to Rydberg states and upper regions of the mixed singlet/triplet state. The present work focuses on the excitation of a

Femtosecond pump-probe techniques combined with a reflectron time-of-flight mass spectrometer are employed to study the dynamics of ammonia clusters excited to the A state. In this paper we present data on the formation of protonated ammonia cluster

The (pre)dissociation of acetone and acetone clusters after excitation to states corresponding to upper {S1,T1} and 3s Rydberg states of the acetone monomer are investigated through femtosecond pump–probe experiments coupled with molecular beam tim

Herein, we report on femtosecond time‐resolved experiments in ammonia clusters. The mechanisms of their ionization and the subsequent formation of the protonated ammonia cluster ions are studied using a femtosecond pump‐probe technique at 620 nm.

During the course of investigating dehydrogenation reactions induced by transition metals, we find that using a carrier gas containing hydrocarbons and ammonia instead of pure helium, in conjunction with a laser vaporization device, enables the facil
