1 H NMR study of the solvolysis of the paramagnetic tetrachloro-bis(imidazole)ruthenium(III) anion in water, methanol, and dimethyl sulfoxide The 1H NMR signals of the Ru(III) species present in solution are considerably broadened and shifted by paramagnetism, but they can be used to follow ch...
在一定的实 验条件下,NMR信号强度与产生该信号的共振核 数目成正比,因此定量核磁共振技术作为新的发 展方向开始被人关注 。在NMR试验中,DMSO.d6是一种常见的重要 试剂,不同厂商、不同批次的DMSO—d6的氘代度 有所不同,因此需要定期检测,确保产品质量。相 对于质谱、傅立叶变换红外等方法,核磁共振检测 收稿...
Considering the CDF of DMSO and water (cf. Fig.7), a similar good agreement of the overall pattern can be obtained between the results of the AIMD and FFMD simulations. The first peak (30 – 240 pm, 145 – 180∘) shows the hydrogen bond between DMSO and water. The second maximum a...

The new complexes have been characterized by IR, UV–Vis and H NMR spectroscopic methods. In addition, the structure of one of the complexes, [RuCl(DMSO)(tcah)]·HO (tcah = thiophene-2-carboxylic acid hydrazide), has been determined by single crystal X-ray diffraction. All the studies ...
