Stimulated Raman spectroscopy has been used in a fast ion beam to measure the hyperfine structure in the 4{ital d}{sup 2} configuration of Y II. A simple theory is provided for the line shape of the coherent two-photon transition which gives a transit-time limited linewidth of 0.9/{ital T}, comparable to the resolution of the laser--radio-frequency double-resonance technique. The hyperfine structure is compared with a multiconfiguration Dirac-Fock calculation and with that of the homologous Sc II ion. This comparison confirms the role of core polarization as a significant factor in the hyperfine structure of these ions.
