摘要：
Excited states of excitonic molecule have been observed for the first time by direct method of giant two-photon absorption in monoclinic ZnP2 single crystal. Two excited states with binding energies 3.3 meV and 1.9 meV have been observed in absorption spectra of intense picosecond laser pulses. First one corresponds to rotational excited state. Interpretation of the second one and details of nonlinear absorption spectra are discussed.
