    "abstract": "We report the observation of ultralong coherence times in the purely\nelectronic zero-phonon line emission of single terrylenediimide molecules at\n1.4 K. Vibronic excitation and spectrally resolved detection with a scanning\nFabry-Perot spectrum analyzer were used to measure a linewidth of 65 MHz. This\nis within a factor of 1.6 of the transform limit. It therefore indicates that\nsingle molecule emission may be suited for applications in linear optics\nquantum computation. Additionally it is shown that high resolution spectra\ntaken with the spectrum analyzer allow for the investigation of fast spectral\ndynamics in the emission of a single molecule.",
