Photoelectron spectroscopy of the deprotonated octatrienoic acid anion,[C7H9–CO2]−,
shows the formation of [C7H9]− and loss of H–at h ν= 4.13 eV. Using velocity map imaging …

The development of tandem ion mobility spectroscopy (IMS) known as IMS-IMS has led to
extensive research into isomerizations of isolated molecules. Many recent works have …

The barrier energies for isomerization and fragmentation were measured for a series of
retinal chromophore derivatives using a tandem ion mobility spectrometry approach. These …

Gas-phase studies of the retinal protonated Schiff base chromophore are reviewed. The use
of action spectroscopy has solidified the understanding of the spectral-tuning mechanisms of …

Collisions between molecules and gas phase targets often lead to various intriguing
processes. Such collisions may induce fragmentation of molecules that can be divided into …
