The theoretical calculations for the low-lying vibrational H atoms adsorbed on the Pt(110) surface are presented. We use the H/Pt(110) model with the conventional ultrahigh vacuum and the density functional theory to study the phonon frequency. The nature of hydrogen atoms, which were adsorbed on the four different sites of Pt(110) surface, is shown. The most stable site of the short bridge is in agreement with previous studies. The highest stretching frequency of 2200 cm⁻¹ and the zero-point energy (ZPE) of the H atom on top site ~ 140 meV are calculated. Our results convincingly demonstrate the need to study the local oscillation to understand the dynamics of this system.

Pt（110）表面上吸附的氢的零点振动

提出了吸附在Pt（110）表面的低层振动H原子的理论计算。我们使用具有传统超高真空和密度泛函理论的H / Pt（110）模型来研究声子频率。显示了氢原子的性质，氢原子吸附在Pt（110）表面的四个不同位置上。短桥最稳定的位置与先前的研究一致。计算出最高拉伸频率2200 cm ^-1和顶部位点〜140 meV的H原子的零点能量（ZPE）。我们的结果令人信服地表明需要研究局部振荡以了解该系统的动力学。
