WebFeb 2, 2024 · Performing measurements at overtones lets users check the validity of the Sauerbrey equation [2]. Resonant frequencies and dissipation measurements at overtones allow also to characterize viscoelastic thin films, particles, molecules or even conformation. More details are given in [7]. Quartz Crystal Microbalance: principles and history WebFor a realistic crystal model, the quality factor Q(k) for the series resonators decreases for the overtone frequencies: So if the crystal is used in its fundamental mode (k = 1) or for an overtone, the other modes (overtones) can be neglected and the crystal can be modelled by only one single series RLC resonant circuit. See Figure 2. Figure 2. ghost town song rolling stones
