    Abstract:
    Abstract NF 3 and N(NO 2 ) 3 are known compounds, whereas the mixed fluoronitroamines, FN(NO 2 ) 2 and F 2 NNO 2 , have been unknown thus far. One of these, FN(NO 2 ) 2 , has now been prepared and characterized by multinuclear NMR and Raman spectroscopy. FN(NO 2 ) 2 is the first known example of an inorganic fluoronitroamine. It is a thermally unstable, highly energetic material formed by the fluorination of the dinitramide anion using NF 4 + salts as the preferred fluorinating agent.

    Abstract Overhauser–DNP‐enhanced homonuclear 2D 19 F correlation spectroscopy with diagonal suppression is presented for small molecules in the solution state at moderate fields. Multi‐frequency, multi‐radical studies demonstrate that these relatively low‐field experiments may be operated with sensitivity rivalling that of standard 200–1000 MHz NMR spectroscopy. Structural information is accessible without a sensitivity penalty, and diagonal suppressed 2D NMR correlations emerge despite the general lack of multiplet resolution in the 1D ODNP spectra. This powerful general approach avoids the rather stiff excitation, detection, and other special requirements of high‐field 19 F NMR spectroscopy.

    The core−shell structure of lycopene micronizates can be verified by employing a combination of solid-state and suspended-state NMR spectroscopy. The type of molecular aggregation of carotenoid nanoparticles can be clearly determined from their characteristic fingerprint pattern in the solid-state NMR spectra.

    Nuclear magnetic resonance (NMR) spectroscopy is the most effective means for structural analysis of substances,which is rapidly developed in recent years. This article reviews applications of one-dimensional nuclear magnetic resonance spectroscopy (1D-1H NMR),2D-1H NMR including COSY(Correlation Spectroscopy),TOCSY(Total Correlation Spectroscopy),NOESY(Nuclear Overhauser Effect Spectroscopy),and ROESY(Rotating Frame Overhauser Effect Spectroscopy) in structure analysis of cyclodextrin and cyclodextrin complexes.

    Polarization enhancement nurtured during attached nucleus testing (PENDANT) NMR spectroscopy gives signals of quaternary carbon atoms in addition to signals indicative of CH, CH2 and CH3 groups. In this study, using product operator theory, analytical description of PENDANT NMR spectroscopy for CHn (ISn, I = 1/2, S = 1/2, n = 0, 1, 2, 3) spin systems are presented. Simulation and experimental results of PENDANT NMR spectroscopy are also presented. Theoretical results are found to be in exact agreement with the simulation results and in good agreement with the experimental ones.
