DESCRIPTION:What happens to a molecule once it has absorbed UV or visible 
 light? How does the molecule release or convert the extra energy it just r
 eceived? Answering these questions clearly goes beyond a pure theoretical 
 curiosity\, as photochemical and photophysical processes are central to nu
 merous domains like energy conversion and storage\, radiation damage in DN
 A\, or atmospheric chemistry. A plethora of theoretical tools have been de
 veloped over the past decades to address these questions by simulating the
  excited-state dynamics of molecules. These methods are often tested and t
 heoretically validated on reduced-dimensionality models or rather simple m
 olecules. \n \nIn this seminar\, I will present a series of examples in wh
 ich studying the photophysics and photochemistry of molecules in the gas p
 hase has highlighted the limitations of current theoretical methodologies 
 and stimulated the development of new strategies for excited-state dynamic
 s. More specifically\, I will focus on the formation of complex photoprodu
 cts\, related to atmospheric chemistry and time-resolved spectroscopy\, an
 d on the description of photoexcitation.
