We describe the sample of energetic single-photon events (Eγ > 15 GeV) collected by L3 in the 1991-1993 LEP runs. The event distributions agree with expectations from the Standard Model. The data are used to constrain the ZZγ coupling and to set an upper limit of 4.1 × 10-6, μB (90% C.L.) on the the magnetic moment of the T neutrino.
