摘要
本文采用U-B力场在位置群近似时对钻石中SiO离子的内振动进行了简正坐标分析,振动频率的计算值与观察值吻合很好。根据简正坐标分析确定的力常数值为从Kr=400,H1=44,H2=60,F=25N·m-1。
Normal coordinate analysis has been carried out for the internal vibrations of SiO ions in zircon using the Urey-Bradley force field. The calculated vibrational frequencies are in reasonably good agreement with those observed- The valus of the force constants so obtained are: Kr= 400,H1=44, H2= 60, and F=25 N. m-1.
