Spectral transients of bright (,40 singlet excitons within the Ell and E-22 manifolds exhibit a photobleach (PB) and a photoabsorption (PA) signal of similar strength. The PA is blue-shifted with respect to the PB-signal by 7.5 meV and is attributed to a transition from the dark singlet exciton (0)A(0) + to a (0)A(0)(-) + (0)A(0)(+) state within the two exciton E-11 manifold.
