hey your ans is
(E.g. in terms of the spectral function S(k,ω)S(k,ω) this means one would get a finite width in ωω-space).

I hope its help you plzz mark me brainliest ans and follow me

spin chains with finite-lifetime quasi-particles.

Raman scattering arises from molecular vibration causing a change in polarizability. This means that intense Raman scattering occurs from symmetric vibrations which induce a large distortion of the electron cloud around the molecule.
