It is a question about Raman baseline fitting?

12 December 2018 0 1K Report

I want to perform baseline correction for a raman data.

Which kind of baseline correction is the best for Raman?

I am using origin. Should I pick up the random baseline points and subtract it or i take an exponential fitted line of these points?
