Nonadiabatic dynamics simulations have become the most fertile branch of chemical physics for modeling photochemical and photophysical ultrafast phenomena in molecules over the last few decades. These approaches deal with the coupled electron-nuclear dynamics in a manifold of electronic states beyond the Born-Oppenheimer (BO) approximation. A substantial body of literature demonstrates the significant role of excited electronic states in various chemical physics phenomena, from photochemistry to electron transfer. These findings have diverse applications, ranging from renewable energy to biophysical processes. Despite the field's maturity, ongoing research continues to unveil new insights. Therefore, serious attention is needed to develop the methodology with proper modeling of excited state dynamics that captures the nonadiabatic effect accurately and meaningfully.
