Clustering the 74 Raman spectra without background corrections applied using first-derivative data. (a) The dendrogram. Labelling from the left-hand side, the red and orange entries are carbamazepine; the green are cimetidene; the light blue and dark blue are two forms of furosemide; the purple are sulfamerazine; the brown are phenilbutazone and the right-hand light and dark green are two forms of mefenamic acid. (b) The MMDS plot. The clusters are well defined but the orange and red (both carbamazepine) are very close to each other.
