00925njm 22002777a 4500 dc Corrales Castellanos, Maria Eugenia author Loriot, Vincent author Balerdi Villanueva, Garikoitz author González Vázquez, Jesús author Nalda Míguez, Rebeca de author Bañares Morcillo, Luis author Zewail, Ahmed author 2014 The correlation between chemical structure and dynamics has been explored in a series of molecules with increasing structural complexity in order to investigate its influence on bond cleavage reaction times in a photodissociation event. Femtosecond time-resolved velocity map imaging spectroscopy reveals specificity of the ultrafast carbon–iodine (C–I) bond breakage for a series of linear (unbranched) and branched alkyl iodides, due to the interplay between the pure reaction coordinate and the rest of the degrees of freedom associated with the molecular structure details. Full-dimension time-resolved dynamics calculations support the experimental evidence and provide insight into the structure–dynamics relationship to understand structural control on time-resolved reactivity Corrales, María E., et al. «Structural Dynamics Effects on the Ultrafast Chemical Bond Cleavage of a Photodissociation Reaction».
