Characterization of heroin samples by 1H NMR and 2D DOSY 1H NMR

Forensic Science International, 2014
Twenty-four samples of heroin from different illicit drug seizures were analyzed using proton Nuclear Magnetic Resonance ((1)H NMR) and two-dimensional diffusion-ordered spectroscopy (2D DOSY) (1)H NMR. A careful assignment and quantification of (1)H signals enabled a comprehensive characterization of the substances present in the samples investigated:

1H‐NMR Microscopy of Tablets *

Journal of Pharmaceutical Sciences, 1995
A 1H-nuclear magnetic resonance (NMR) microscopy method was utilized for the first time to determine the porosity distribution of physically intact tablets. The main advantage of this newly developed method was that porosity cross sections through whole tablets or specific locations could be obtained without mechanically destroying the tested tablet ...

1H-NMR and 77Se-NMR in CsHSeO4

Solid State Ionics, 2005
Abstract Measurements of 1 H-NMR and 77 Se-NMR have been conducted with CsHSeO 4 , in order to clarify dynamics of proton and SeO 4 tetrahedron which is related to transport of proton below and above T c  = 401 K. An NMR absorption line is observed in 1 H-NMR measurement and its line width decreases with increasing temperature below T c , due

1H and 2H NMR mobility in cellulose

Carbohydrate Polymers, 2001
Abstract Mobility of water in cellulose was studied by solid-state 1H and high-resolution 2H NMR as a function of moisture content within the unfreezable moisture range (0–19% dry basis). Measurements of relative mobilities were based on relative intensities, transverse and longitudinal relaxation times and lineshape analysis.

1H-NMR characterization of cucumber peroxidases

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1991
Two peroxidase isoenzymes from Cucumber seedlings, one acidic (pI = 4) and one basic (pI = 9), were characterized by 1H-NMR spectroscopy. The NMR spectra were obtained in the native (ferric high-spin) and cyanide ligated (ferric low-spin) forms of both isoenzymes. The NMR spectral comparison of paramagnetically shifted resonances with those of the well
