The reflection spectrum of the fust singlet charge transfer transition of anthracene-PMDA (pyromeflitic dianhydride) crystal has been obt.dned at temperatures close to 2 K. The spectrum is polarized along the stack axis and consists of a series of vrbronic bands, approximately 500 cm-l wide, with im
