Near‐infrared (NIR) Fourier transform (FT) Raman spectra of four steroid hormones labeled with organometallic fragments, five steroid hormones and five model organometallic complexes were measured at room temperature. The objective was to determine which particular molecular vibrations of the steroid hormones might be best suited for any future quantitative analyses. On the basis of this FT‐Raman study, a classification of the most important vibrations as a function of their relative band intensities is proposed, i.e. v (Co 2 ‐alkyne) ≈ v (Co‐Co) < v (C≡C) ≈ v (C‐C) Cp (Cp = β 5 ‐C 5 H 5 ) < v (C≡O) < v (C≡N).
