We study excitons in crystalline thin fiims of the archetype molecular compound: 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) by measuring the photocurrent response under small electric fields (< lo4 V/cm). A previously uncharacterized exciton at a wavelength of A = 590 nm, or at 2.10 eV abo
