摘要
本文发展了一种用于研究吸附分子体系振动耦合效应的方法.该方法适用于具有二维面心点阵结构的吸附分子体系。借助于体系的IRAS及EELS实验资料,该方法能很容易确定吸附分子之间的侧向作用力常数及分子内部力常数,本文还具体讨论了Cu(111)-CO-(√3x√3)R30°结构中的CO分子体系的振动耦合效应。
A new method is developed to study the vibrational coupliny of adsorbate molecules with a 2D fcc structure. This method can be used to determine the force constant of adsorbate molecule itself and the interaction force constants between adsorbate molecules with the help of the IRAS, EELS and LEED experimental data of adsorbate. The vibrational coupling effcts of CO molecules on Cu(111) face with (3^(1/2) ×3^(1/2))R30° structure are discussed in detail.
