From study of the ν(CC) Raman band of 4‐octyne (a proton acceptor) is is shown that, whenever the solvent is respectively a poor or a good proton donor, the formation of the hydrogen bond increases or decreases the integrated intensity of the band comparatively to pure liquid. From study of the ν(CC) Raman band of 1‐octyne (an electron acceptor) it appears two groups of electron donor solvents: (i) solvents whose effect is compatible with solvent — cage model, (ii) solvents for which the intensity of the ν(CC) band depends of ionization potential, the result suggests a charge‐transfer model.
