摘要
本文用基于精确二分量哈密顿(exact two-component Hamiltonian)的相对论含时密度泛函理论(time-dependent relativistic density functional theory)计算了Yb和YbO的电子激发态,并利用对称性、自然原子轨道对激发态性质和归属进行了详细分析,所得结果支持实验对YbO基态与激发态的指认.
The low-lying electronic states of Yb and YbO are investigated by using time-dependent relativistic density functional theory, which is based on the newly developed exact two-component Hamiltonian resulting from symmetrized elimination of the small component. The nature of the excited states is analyzed by using the full molecular symmetry. The calculated results support the previous experimental assignment of the ground and excited states of YbO.
