From: Exciton binding energy and hydrogenic Rydberg series in layered ReS2
(a) Polarization-resolved PL and RC spectra of bulk ReS2 recorded in two linear polarisation with the angle between E and b equal to 33° (red line) and 113° (blue line). (b) and (c) Experimentally and theoretically obtained transition energies for the 3D exciton states as a function of the quantum number n, for the X1 and X2 excitons, respectively.
