10 de sept. de 2024 · This post introduces NMR basics, focusing on the analysis and interpretation of the 1-D 1 H and 13 C NMR spectra. An overview of NMR basics, including principles, is available on the JEOL website. Information available from NMR charts
16 de sept. de 2024 · qNMR stands for “quantitative NMR” and refers to the use of NMR to determine the concentration of one or more chemical species in solution.
11 de sept. de 2024 · Solid-state NMR is one of the most powerful analytical methods for the structural characterization and dynamics of polymers. Owing to its intrinsically low signal sensitivity, however, analysis...
20 de sept. de 2024 · CP3 is a parameter which helps to assign structure and stereochemistry by comparing experimental and calculated NMR spectra. The calculation of CP3 is a three step process: Enter data (separated by commas in each line)
25 de sept. de 2024 · Methoxy groups have a distinct NMR signature that make them easy to spot in virtually every case. The basic pattern is a singlet integrating to 3 and ranging between 2.4 to 4.4 ppm on a 1H NMR spectrum (assuming no overlap with other resonances).
5 de sept. de 2024 · Combining benchtop NMR with hyperpolarization methods such as d-DNP, SABRE, or photo-CIDNP enhances the sensitivity and enables the performance of fragment screening in an agile and high-throughput manner. Abstract.
15 de sept. de 2024 · Prussian blue analogue (PBA) nanospheres (NS), designed as advanced electrocatalysts, are based on Ni 3 S 2 @FeCoNi and phosphorization. Thermal oxidation can allow NS to undergo microstructural collapse and form nanorubble (NR). NR obtained at 325 °C has a lower overpotential (230.0 mV) than NS.
