看起来确实挺复杂,先从log文件结尾的出错提示开始:
Problem with coordinate system.
说明是坐标的问题——gaussian不知道下一步的坐标怎么处理了。
一般这种原因是由于优化角度时180度是最大值,gaussian不知道181度其实就是179度。这是gaussian长久以来的一个问题。一般可以从降低体系对称性,修改初始构象,增加虚原子手工写内坐标强制内坐标优化等方法去规避。
你的体系是按照C无穷V的对称性开始的,出这个错误也在情理之中的。
但再仔细看,你初始为Li……H—F构型,怎么从化学的角度感觉不太对呢。。F的电负性很强,我猜应该是Li……F—H构型才对吧。同时不从直线结构开始,把角度改成179,增加nosymm字,然后优化,结果顺利。
不知道你到底想研究什么,也不知道你从哪里文献搞来的你说的那种初始结构,我就乱说一气了。
