Obtaining Poles and Zeros from frequency response
There is a little uncertainty in my mind what the OP is asking for so I'll try and generalize a little. Look at the drawing below (top half) - it shows three examples of bode plots for 2nd order systems where damping has a few values: -



Below the three bode plots are examples of the pole zero diagram and how it relates to the bode plot. Mathematically they are very connected (see the formulas) and, for pure 2nd order systems, it should be a fairly easy task to convert the bode plot into a fairly precise pole-zero diagram. However, for quite small subtleties in the bode plot there can be a much wider range of poles and zeroes especially if you include higher orders than two.

What I'm trying to say is that it can be quite difficult/imprecise going from bode to pole zero diagrams but not the other way round.
