    "abstract": "We report on the first spectroscopic observation of the rotational Doppler\nshift associated with light beams carrying orbital angular momentum. The effect\nis evidenced as the broadening of a Hanle/EIT coherence resonance on Rb vapor\nwhen the two incident Laguerre-Gaussian laser beams have opposite topological\ncharges. The observations closely agree with theoretical predictions.",
