In a first, “photophysical” example the creation of electron wavepackets in molecules by ultrashort laser pulses, and their attosecond dynamics<span> </span></span><span style="font-family: arial, sans-serif;">and spectroscopic response will be followed with the help of time-dependent, correlated<span> </span></span><span style="font-family: arial, sans-serif;">electronic structure methods. In a second example steps towards “photochemistry” are<span> </span></span><span style="font-family: arial, sans-serif;">taken by considering photoswitching of azobenzene molecules in constraining environments. Here, non-adiabatic molecular dynamics with surface hopping allow for detailed<span> </span></span><span style="font-family: arial, sans-serif;">insight into the mechanism of photoinduced trans-to-cis isomerization. As another photochemical process, photocatalytic water splitting in porous, carbon and nitrogen containing<span> </span></span><span style="font-family: arial, sans-serif;">layered materials will be considered. Finally, if time permits, “photochemistry without<span> </span></span><span style="font-family: arial, sans-serif;">light” will be discussed for the example of isomerization reactions of molecules in optical<span> </span></span><span style="font-family: arial, sans-serif;">cavities, a new, emerging field in chemistry.</span></p><div style="color: #000000;
