The photodissociation of CH 3 I in the red edge of the A-band: Comparison between slice imaging experiments and multisurface wave packet calculations
TL;DR: A general qualitative good agreement has been found between theory and experiment, the most important discrepancies being in the I((2)P(3/2)/I( *)((2) P(1/2)) branching ratios.
Journal ArticleDOI
Slice imaging of the photodissociation of acetaldehyde at 248 nm. Evidence of a roaming mechanism
Luis Rubio-Lago,G. A. Amaral,Andrés Arregui,J. G. Izquierdo,Fengyan Wang,D. Zaouris,D. Zaouris,Theofanis N. Kitsopoulos,Theofanis N. Kitsopoulos,Luis Bañares +9 more
TL;DR: The photodissociation of acetaldehyde in the molecular channel yielding CO and CH(4) at 248 nm has been studied, probing different rotational states of the CO(nu = 0) fragment by slice ion imaging using a 2+1 REMPI scheme.
Journal ArticleDOI
Imaging the radical channel in acetaldehyde photodissociation: Competing mechanisms at energies close to the triplet exit barrier
TL;DR: The photodissociation of acetaldehyde in the radical channel has been studied at wavelengths between 315 and 325 nm using the velocity-map imaging technique, and the fragments' KER is characterized, as well as the energy partitioning for the radical fragments are determined.
Journal ArticleDOI
Imaging the molecular channel in acetaldehyde photodissociation: roaming and transition state mechanisms.
Luis Rubio-Lago,Luis Rubio-Lago,G. A. Amaral,Andrés Arregui,Jesús González-Vázquez,Jesús González-Vázquez,Luis Bañares +6 more
TL;DR: The roaming dynamics in the photodissociation of acetaldehyde is studied through the first absorption band, in the wavelength interval ranging from 230 nm to 325 nm, using a combination of the velocity-map imaging technique and rotational resonance enhanced multiphoton ionization spectroscopy of the CO fragment.
Journal ArticleDOI
Solvent-Free MALDI Investigation of the Cationization of Linear Polyethers with Alkali Metals
TL;DR: The MALDI technique with solvent-free sample preparation has been applied to evaluate relative gas-phase affinities of polyether chain polymers with alkali metal cations and shows that the polyether-cation aggregation efficiencies decrease systematically with growing cation size.
