In the Shpolskii effect, aromatic compounds dissolving in n ‐alkanes of suitable lengths show quasi‐linear absorption and emission spectra when frozen to 77° K . Mixed crystal such as naphthalene dissolving in durene does not show fine structures above 20° K . This difference is likely due to the fact that the lattice vibrations in n ‐alkanes have very low frequencies as shown in their Raman spectra at 77 °K .
