Studies on the NMR methodology for characterizing the structure of polymers and biopolymers based on the understanding of the NMR chemical shift/structure correlation using solution-state and ...

为解决 1H NMR 谱预处理及多变量分析需多软件和人工干预、效率与重复性差的问题，研究人员开发 Interval Resonance Analysis（InRA）工具。其用于 1H NMR 多变量分析，在甜菜根提取物鉴别中分类准确率≥88.9%，提升了分析效率与通用性。

尽管13 c-nmr存在局限性，但它提供了仅使用1 h-nmr无法获得的宝贵信息。 例如，它可以识别一级碳、二级碳、三级碳和四级碳。 因此，在NMR实验室中，13 C-NMR和1 H-NMR通常联合使用，作为测定分子结构的基本方法。

低场 1 h nmr 光谱技术具有设备成本低、操作简便、无需复杂维护等优点，相比传统的高场 nmr 更易普及。 它作为一种代谢组学筛查工具，有望弥补传统筛查方法的不足，提高宫颈癌早期诊断的准确性，从而帮助更多女性在疾病早期得到及时治疗，改善预后，降低宫颈癌的发病率和死亡率，为女性健康 ...

These tests confirmed the applicability of the 1.3 GHz NMR first-of-a-kind spectrometer, yielding high-resolution liquids and solids NMR spectra at 1.3 GHz. The results demonstrated increased ...

This Perspective seeks to reconnect the current practice of nuclear magnetic resonance (NMR) spectroscopy in chemical structure and quantitative (qNMR) analysis with its roots in classical physics and ...

The 1 H NMR spectrum demonstrates that this repellent's formulation mostly consists of ethanol, water, and DEET. Figure 1. 1 ...

This small, thus broadly deployable, NMR system can find applications in online, on-site, or on-demand multinuclear molecular fingerprinting. Concretely, the wideband spectrometer performs NMR ...

For this reason, 13 C-NMR and 1 H-NMR are often used jointly in NMR laboratories as a basic approach for molecular structure determination. 14. Table 1: Comparison of 1 H and 13 C NMR properties. 15 .
