The measurements of the spectral response of single atoms that are trapped and strongly coupled to the field of a high finesse optical resonator were described. A complete probe spectrum for one-and-the-same atom was recorded by alternating intervals of probe measurement and of atomic cooling. The vacuum Rabi splitting is thereby measured in a quantitative fashion for each atom by way of a protocol that represents a first step towards more complex tasks in quantum information science. The spectra contain detailed quantitative information about the coherent coupling and far-off-resonance trap (FORT) shifts for each atom and the information indicates that the coupling is in a narrow range of near-maximal values.
