Abstract

Resonant Raman measurements of α-hexathiophene at 33 K have identified over ten vibrational modes that couple to electronic excitations in the single crystal. These excitations at 2.066 eV and 2.068 eV with a width of 2meV have been tentatively identified as bound singlet Frenkel excitons or a triplet Frenkel exciton.
