In the nematic state of FeSe, B1g Raman intensity is suppressed at low frequencies because the orbital content of the Fermi pockets becomes nearly mono-orbital, and charge-conservation vertex corrections cancel the resulting s-wave component of the Raman vertex.

Raman response in the nematic phase of FeSe
In the nematic state of FeSe, B1g Raman intensity is suppressed at low frequencies because the orbital content of the Fermi pockets becomes nearly mono-orbital, and charge-conservation vertex corrections cancel the resulting s-wave component of the Raman vertex.
