    "abstract": "We study the behavior of the group velocity of light under conditions of\nelectromagnetically induced transparency (EIT) in a Doppler broadened medium.\nSpecifically, we show how the group delay (or group velocity) of probe and\ngenerated Stokes fields depends on the one-photon detuning of drive and probe\nfields. We find that for atoms in a buffer gas the group velocity decreases\nwith positive one-photon detuning of the drive fields, and increases when the\nfields are red detuned. This dependence is counter-intuitive to what would be\nexpected if the one-photon detuning resulted in an interaction of the light\nwith the resonant velocity subgroup.",
