Experimental and theoretical research on nonadiabatic effects in metals is briefly reviewed. It is shown that these effects are most manifest in optical phonon spectra at small wave vectors q satisfying the condition qv_F < ω₀(q), where v_F is the electron Fermi velocity, and ω₀(q) is the phonon frequency. Various theoretical approaches to calculating nonadiabatic effects are examined. Fröhlich’s phenomenological field-theoretical model, the most widely used in such calculations, is discussed in detail, some aspects of its application are considered, and its efficiency as a tool for studying nonadiabatic effects is demonstrated.
