Generally the linewidth of a Raman peak indicates the lifetime of phonon i.e. if the linewidth increases w.r.t say some x parameter implies phonon decay as x increases/decreases. What if we observe curve parallel to x axis? does it implies absence of phonon decay or decay is present but is independent of x?
Hi- without knowing anything else, I presume the conclusion is that the linewidth is independent of x, and therefore the inverse linewidth (lifetime) is independent of x.
Dear Surya Bhaskaram,

Dear Surya Bhaskaram,
Here below are numerous examples of Raman specters with their specific interpretations. It should be very useful for a practical training in behind specters physical processes interpretations.

Hugh J Byrne thanks a lot sir, your answer is quite helpful and has helped to interpret my result better.
Len Leonid Mizrah thanks a lot sir for introducing me to such an useful database. This will definitely help me now and in future for better interpretation of results.
