When mounting the resonator horizontally in an open cell (F) and letting the liquid evaporate, one observes coupled resonances (A–C). The vertical enlargement (D,E) shows the coupled resonances on the overtones. Because of the reduced wavelength, these are more densely spaced than the coupled resonances on the fundamental mode. Furthermore, and more importantly, they occur at a much-reduced amplitude.
