Structural dynamics effects on the ultrafast chemical bond cleavage of a photodissociation reaction Corrales Castellanos, Maria Eugenia Loriot, Vincent Balerdi Villanueva, Garikoitz González Vázquez, Jesús Nalda Míguez, Rebeca de Bañares Morcillo, Luis Zewail, Ahmed 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 2024-01-31T08:41:12Z 2024-01-31T08:41:12Z 2014 journal article Corrales, María E., et al. «Structural Dynamics Effects on the Ultrafast Chemical Bond Cleavage of a Photodissociation Reaction».
