这个问题在谷歌上找到的答案是：To my knowledge Gaussian does not do frequency calculations in PBC.
Their manual says nothing about this and I found that out when their support staff told me.
I would recommend using either Crystal (Gamma Point freqs only) or VASP if you've got access to those codes. Or else there's always PWSCF or Abinit which do have that capability.
