概要
- 論文の詳細を見る
The frequencies of the translational and rotational vibrations (in optical branches) in the cubic NaClO_4 crystal, which is one of the complex crystals with simplest structure, are expressed in terms of the force constants of the interionic forces. The expression obtained with respect to the translational vibration is quite similar to that in the case of isotropic simple crystals, which is already known. Furthermore, by assuming reasonable values for these force constants, the orders of magnitudes of the both frequencies are estimated and compared with one another. The comparison shows that the both frequencies are nearly of the same order of magnitude.
