Very long-range correlations ((n)J(C,H) n > 3) in HMBC spectra
(NATURAL PRODUCTS INC, 2008)
The structural elucidation of natural products and complex organic molecules relies heavily on the application of proton detected heteronuclear NMR. Among these techniques, the HMBC NMR experiment remains as the most popular ...
An analysis of network filtering methods to sovereign bond yields during COVID-19
In this work, we investigate the impact of the COVID-19 pandemic on sovereign bond yields. We consider the temporal changes from financial correlations using network filtering methods. These methods consider a subset of ...
Use of long-range C-H ((n)J n > 3) heteronuclear multiple bond connectivity in the assignment of the C-13 NMR spectra of complex organic molecules
(BENTHAM SCIENCE PUBL LTD, 2001-03)
The structural elucidation of complex organic molecules relies heavily on the application of proton detected heteronuclear NMR. Among these techniques, the HMBC NMR experiment is probably the most useful 2D NMR method The ...
Multiple minima hypersurfaces procedures for biomimetic ligands screening
(2011-09-08)
In this work the interaction of the pesticide carbaryl with two groups of biomimetic ligands, peptides and MIPs was screened by multiple minima hypersurfaces (MMH) procedures, through the AM1 semiempirical method. Data ...

The structural elucidation of complex organic molecules relies heavily on the application of proton detected heteronuclear NMR. Among these techniques, the HMBC NMR experiment is probably the most useful 2D NMR method. The ...
Influência da smear layer na profundidade de desmineralização e na espessura de camada híbrida formada por sistemas adesivos atuais.
(Universidade Federal de Santa MariaBROdontologiaUFSMPrograma de Pós-Graduação em Ciências Odontológicas, 2010-02-24)
The aim of this study was to evaluate the thickness of hybrid layer and the depth of demineralization produced by adhesive systems applied in dentinal surfaces submitted to
different treatments. Dentin slices extracted ...
A new tropane alkaloid and other constituents of Erythroxylum rimosum (Erythroxylaceae)
(2013-05-01)
A new tropane alkaloid, named the 7β-acetoxy-3β,6β- dibenzoyloxytropane (1), was isolated from a methanol extract of Erythroxylum rimosum O.E. Schulz leaves. Other known compounds were detected, including quercetin, ...
