Spectral transfer functions are computed for a model consisting of one elastic layer over a homogeneous elastic half‐space. Represented in the time domain, the transfer functions are compared with theoretical seismograms for various horizontal distances. The diagnostic diagrams show that the P̄ +‐ ‐mode, the contribution of which is important in the generation of the PL ‐waves, is not the continuation of the first locked shear mode below the cut‐off frequency.
