the study of the direct photodissociation ( A band) and electronic predissociation ( B band) of methyl iodide along with the detection and characterization of transient species and the study of cluster dissociation, as a case example for femtosecond velocity map imaging, are presented and discussed...
The femtosecond pump-probe technique provides information on ultrafast dynamics in molecular systems. Combining this technique with photo-ion velocity map imaging provides direct information on the kinetic energy and angular distribution of the photofragments. We report experimental results on (multi) ...
