Well defined resonances are observed in the spectra. A strong anticrossing between two transitions is observed in all samples, which cannot be accounted for by a purely excitonic model. The coupling between the mixed exciton-LO phonon states is calculated using the Fr\\\"{o}hlich Hamiltonian. The excitonic polaron energies as well as the oscillator strengths of the interband transitions are determined.
