✦ Synopsis


Raman excitation proÐles (REPs) of several totally symmetric vibrations of 2,2º-dipyridylamine (DPA) were measured and analysed. Possible molecular structures and other interesting properties of the molecule in the excited electronic states are discussed. Normal-mode characteristics are also described. Of the three excited states found from the electronic absorption spectra, it is shown that the molecular geometry is not signiÐcantly changed in the lowest excited singlet state (assigned as the state).
