ESPINOZA, Luis; GARBARINO, Juan A.; CHAMY, M. Cristina  e  PIOVANO, Marisa. PULSED FIELD GRADIENTS IN NMR HIGH RESOLUTION EXPERIMENTS . J. Chil. Chem. Soc. [online]. 2004, vol.49, n.2, pp.189-195. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072004000200016.

High-resolution NMR spectra of selective 1D, 2D homonuclear and 2D heteronuclear experiments were registered of the mixtures of the natural products 3-4 and the methyl esters (5-6) and acetyl derivates (7-8) of the natural product 1-2, using Pulsed Field Gradients (PFGs) technique. Thus, it was possible to obtain high-resolution spectra, smaller time of acquisition and larger structural information
