I was working today with “R” to get more patterns with the Corrgram. In the demo raw spectra I wanted this time to look to a band as much Gaussian as possible. I select it and trim the spectra to that region treated with the MSC (“Multiple Scatter Correction”).
After I decided to apply another Math treatment (SG filter 2ª derivative). With the 2ª derivative the peak maximum in MSC, change to peak minimum.
The idea of this post is to look to the patterns and understand this with the wavelengths correlation matrix:
With MSC Treatment:
With SG 2ª derivative:
