摘要：
We have incorporated the translational-rotational (TR) coupling effects in the framework of three body force shell model (TSM) to develop an extended TSM (ETSM). This ETSM has been applied to reveal the second order elastic constants (C(11), C(12) and C(44)) in the dilute regimes 0<x<1 in the temperature range 60K <= T <= 300K. The anomalous elastic behaviour observed in C(44) in Brillouin scattering measurements for the composition x=0.20, 0.30 and 0.59 has been predicted well by ETSM results in the orientationally disordered (NaCN)(x)(NaCl)(1-x) mixed crystals. Besides, the results on cohesive and thermal properties are also discussed.
