It is shown experimentally that, in stimulated Raman spectroscopy, electrostriction induced by the pump laser gives rise to a non‐resonant signal detected on the probe laser. This phenomenon limits the detectivity of the experiment. A qualitative interpretation is given. © 1997 by John Wiley & Sons, Ltd.
