We report a solid-state NMR study of synthetic eumelanins prepared by oxidation of 5,6-dihydroxyindole (DHI) selectively 13C-labeled at positions 2 or 3 of the indole ring. The 13C-1H couplings have been used to quantify the carbons by selecting the

PARSOL © 1789 exists in solution in three tautomeric forms: two cis-enols and a β-diketone. The enol forms predominate. Irradiation of a very dilute solution of PARSOL © 1789 in acetonotrile with a Xenon lamp increases the percentage of β-diketon

Hartmann–Hahn inversion–recovery cross-polarization magic-angle spinning experiments were performed for all types of protonated carbons (CHn with n=1, 2 and 3). The resulting non-exponential decays were analyzed using both a simple memory functio

This paper presents a 13C CP/MAS NMR study of the melanin pigments obtained through natural and synthetic origins: sepia-melanin from squid ink and three synthetic 5,6-dihydroxyindole-melanins prepared using different non-enzymatic oxidation pathways

In this Note we present the advantages of 1H magic-angle spinning nuclear magnetic resonance (MAS-NMR) for the investigation of surfactant suspensions via transverse relaxation rate (R2) measurements. 1H-relaxation rates can be determined by the clas
