This chapter discusses short pulse photoexcitation in organic materials, mostly organic molecular crystals, and the resulting time dynamics of excited states as can be observed by detecting photoluminescence and photoconductivity. The chapter will review the electronic detection of a transient photoconductivity after photoexcitation and the relevant experimental limits. It will then discuss the typical photoluminescence dynamics expected in molecular crystals when initially photoexcited singlet excitons can undergo fission into triplet excitons, and the related onset of photoconductivity because of exciton dissociation. ...
