Grosmaire, L.; Delarbre, J.-L. published an article in 2012, the title of the article was Vibrational spectra of 6-methyluracil, 6-methyl-2-thiouracil and their deuterated analogues.Name: 6-Methylpyrimidine-2,4(1H,3H)-dione And the article contains the following content:
FTIR and Raman spectra of 6-methyluracil (6MU), 6-methyl-2-thiouracil (6M2TU) and the deuterated forms were recorded and analyzed in the regions 400-4000 cm-1 and 100-4000 cm-1, resp. The vibrational spectra are assigned using the frequency shifts upon N-deuteration, especially for bands due to NH modes. For both mols., the isotopic ratio frequency was calculated for each NH/ND vibrations. The sulfur substitution at C2 position in the 6MU mol. has an effect on the N1H and N3H vibrational frequencies. The assignments of C2=O and C4=O modes were supported by the absence of the C2=O group in the thio-derivative The experimental process involved the reaction of 6-Methylpyrimidine-2,4(1H,3H)-dione(cas: 626-48-2).Name: 6-Methylpyrimidine-2,4(1H,3H)-dione
