On July 3, 2014, Sasidharanpillai, Swaroop; Loppnow, Glen R. published an article.HPLC of Formula: 626-48-2 The title of the article was Initial Excited-State Structural Dynamics of 5,6-Dimethyluracil from Resonance Raman Spectroscopy. And the article contained the following:
In order to understand the effect of Me substitution patterns on the initial excited-state structural dynamics of uracil derivatives, we measured the resonance Raman spectra of 5,6-dimethyluracil (5,6-DMU). The results show that the resonance Raman spectrum is a combination of that of 5-methyl- and 6-methyluracil. The resonance Raman excitation profiles (RREPs) and absorption spectrum are simulated with a self-consistent, time-dependent formalism to yield the excited-state slopes and broadening parameters. The initial excited-state structural dynamics occur primarily along the C5=C6 stretching mode, as expected, but with lesser excited-state slopes along each mode compared to 5-methyluracil and 6-methyluracil. This study along with previous experiments with different uracil derivatives show that the presence and positions of the Me groups seems to determine the partitioning of initial excited-state structural dynamics. The experimental process involved the reaction of 6-Methylpyrimidine-2,4(1H,3H)-dione(cas: 626-48-2).HPLC of Formula: 626-48-2
