Single photons from single emitters are good candidates for a high-quality single-photon source which is essential in current quantum optical experiments and applications. Because the statistics of emitted photons is mainly determined by the energy level structure of the system, knowing the correct level scheme and the transition rates between levels is of primary importance. In this work, the energy level scheme and the photon-emission statistics of a single terrylene molecule are studied by measuring the second-order correlation function and the time trace of the emitted photons. The details in the measurement and analysis are discussed, and a more advanced energy-level structure of the terrylene molecule is suggested.
