摘要：
The dielectric response spectrum for antimony sulfoiodide has been computed using a model in which the material is simulated by a damped double well oscillator. It is found that with the use of simple damping and relaxation terms and realistic well parameters the experimental dielectric response, including the central peak, can be reproduced quite closely. The choice of well depth, in particular, plays a major role in determining the frequency of the first peak above the soft mode.
