The present study focuses on the simulation of these experiments using electronic structure calculations and nuclear wavepacket dynamics propagations. The simulation of the evolution of the wavepacket enables a calculation of spectroscopic observables using rigorous quantum mechanical approaches. This approach has been applied to simulate the VUV time-resolved photoelectron spectroscopy (TRPES) spectra of cyclopropane (C₃H₆) and nitromethane (CH₃NO₂).enFemtosecondUltrafast spectroscopyQuantum chemistryQuantum dynamicsCyclopropaneNitromethaneThesis
