老师您好,请问这种问题怎么回答“* When the authors perform singlet-to-triplet TDDFT calculations based on equilibrium S0 geometries to « dissect the nature of the T1 state », how do they know that the lowest triplet state obtained from this calculation corresponds to the T1 state they characterized before by optimizing the geometry of the T1 state from the S0 equilibrium geometry? How can they be sure that there is no crossing between the different triplet states? ”
The wavefunction of transition metals is usually multiconfigurational in nature and some comment regarding this problem is needed. The works on YCn for such systems at high level of theory are available and may be consulted.请问上面的第一句话是什么意思呀?需要看什么资料呀?第二句是让我参考YCn是计算方法吗?请指点一下,谢谢!
sob老师,借助Multiwfn+cubegen来做静电势的分子定量分子表面分析:当中 Run the command like below in MS-DOS/Linux/Mac OS X command-line window. (Beware that the N-phenylpyrrole.fch
provided herein may or may not be incompatible with your cubegen version)
cubegen 0 potential N-phenylpyrrole.fch result.cub -5 h <cubegenpt.txt
这一步怎么做
A:
命令行界面下输入cubegen 0 potential N-phenylpyrrole.fch result.cub -5 h <cubegenpt.txt
运行就完了
cubegenpt.txt是Multiwfn生成的
cubegen是高斯自带的
Q:
cubegen是把chk文件拖入命令窗口就醒了么
A:
file-save visualization state
你执行那条命令
cubegen一般用命令行方式调用
把.vmd文件里的相应路径也进行修改
Q:
是这样的么
[图片]
A:
别先启动cubegen
直接输入命令
打开.vmd文件自行分析改该哪个
Q:
[图片]
这样么
A:
进g09w目录再输入
Q:
是不是还需要加入环境变量啊
A:
否
Q:
我安装在C盘了,怎么打不开~
[图片]
A:
学学DOS基础
Q:
找到了
打开了,然后再输入cubegen 0 potential N-phenylpyrrole.fch result.cub -5 h <cubegenpt.txt ?
问一下,文献里常见”structures were optimized at the broken symmetry unrestricted B3LYP level with the following basis set"其中的broken symmetry究竟指的是什么呢,具体在高斯计算中,关键词是什么呢
