Abstract
The model for the IC transition in quartz is discussed, where the observed long-period IC modulation is interpreted as the third harmonic of the fundamental short-period modulation with the IC vector close to the b/3. (In this model the fundamental modulation is attenuated by the Debye–Waller factor and is not observed in the diffraction experiments). It is shown that the amplitude of the IC third harmonic (particularly its acoustic components) can be larger than that of the fundamental modulation near the lock-in transition to the b/3 phase, and subsequently it is not strongly attenuated by the D–W factor.
