Proton (1H) NMR Spectroscopy

1992
1H NMR spectroscopy can be used for the characterization and classification of lignins and determination of lignin structure. Ludwig (1971) reviewed the literature dealing with the 1H NMR spectroscopy of lignins through 1968, and a comprehensive 1H NMR study of lignins and lignin model compounds was published in 1964 by Ludwig et al. (1964a,b). In this

1H- and 13C-NMR Spectra of Fenobam

Journal of Pharmaceutical Sciences, 1983
Abstract □ 1H- and 13C-NMR data and spectral assignments are reported for fenobam using noise modulated gated, single frequency off resonance, and single frequency selective proton decoupling techniques.

Analiza motornih benzina 1H NMR spektrometrijom

2006
Prema zahtjevima norme, koja se odnosi na zahtjeve i metode ispitivanja bezolovnih motornih benzina (EN 228:2004), dozvoljena količina benzena u motornim benzinima je svega 1vol.%, s tendencijom smanjivanja njegove količine, što zahtjeva sve osjetljivije analitičke postupke određivanja, kao i validirane metode određivanja.

1H NMR METABOLOMSKA ANALIZA MEDA

2022
Metabolomika je nova znanstvena disciplina koja proučava kemijske i biokemijske procese koji se tiču cjelokupnog staničnog metaboloma. Spregnuta sa spektroskopijom NMR predstavlja dobru alternativu brojnim analitičkim metodama korištenima u analitici prehrambenih proizvoda. Med je izrazito vrijedna i cijenjena namirnica u cijelom svijetu.

1H NMR studies of oligosaccharides

1993
Abstract Proton NMR is a very valuable technique for the structural analysis of oligosaccharides since it is possible to determine primary sequence as well as three-dimensional structure. In view of their branched nature, there is at present no cyclical degradative chemical or enzymatic sequencing strategy for oligosaccharides which ...
