[交流] 【求助】求spin-unstricted 解析已有2人参与

Spin unrestricted: When checked, indicates that the calculation will be performed using different orbitals for different spins. This is known as a 'spin-unrestricted' or 'spin-polarized' calculation. If unchecked, the calculation uses the same orbitals for alpha and beta spins. This is known as a 'spin-restricted' or 'non-spin-polarized' calculation. Default = unchecked

Use formal spin as initial: When checked, indicates that the initial value for the number of unpaired electrons for each atom will be taken from the formal spin introduced for each atom. This starting value will be subsequently optimized during the calculation. Default = checked.

不知道 是否用默认!!

这个和你计算的体系有关,如果体系中有原子有开壳层(具体说应该是亚层电子层有非成对电子,比如铁)的话就需要勾选。(个人理解)
