[交流] 求助：如何模拟无机材料红外光谱

以金属铝为例，

1. File->Create Molgroup,
2.Edit->PBC,
Lattice Dimensions选择Three,
Minimum Lattice System选择Cubic,
Enable space group symmetry, 选择Current Space Group:225(Fm-3m)
Cell lengths:4.0495
Contents选项卡symbol选择Al, Highlight点Add
晶体结构完成，close
3. Calculate Gaussian
Job Type选择opt+Freq, submit, Ok...

结果很快报错，信息如下：
Severe Error Message #2070
The processing of the last link ended abnormally. All processing has been aborted.

Gaussian 03W中信息如下：
