Kohler Nature As is customary in the literature on DNA, the terms 'excimer' and 'exciplex' will be used essentially synonymously in this text to describe the formation of a (comparatively long-lived) bound complex of two nucleobases upon excitation with shared electron density between them regardless of whether the two nucleobases are identical or not. Strictly speaking, the definition of an excimer or exciplex (as 'excited homodimer' or 'excited heterodimer', respectively) describes the formation of a bound dimer in the excited electronic state from two units that are not connected in their ground state, while the nucleobases as the chromophores of interest in a di- or oligonucleotide are linked via the sugar-phosphate backbone. But the important point in the present case is the formation of a bound complex with shared electron density between the two bases on excitation. Accordingly, the two nucleobase chromophores can be regarded as electronically unbound in the ground state, the bound state arises on electronic excitation of a subunit only. An exciplex with two different chromophores usually implies at least some charge transfer (CT) character of the excited state due to the different ionization energies and electron affinities of the subunits, an excimer may be neutral regarding the charges on two identical subunits 2005 436 1141 1144
