Analysis of the 1H NMR spectra of substituted fluorenyl carbanions

Journal of Magnetic Resonance (1969), 1970
Abstract The 1H NMR spectra of 2-methylcarbazole nitranion, bifluorene dianion, and four substituted fluorenyl carbanions have been analyzed for chemical shifts and coupling constants. Analysis of these substituted derivatives confirm the earlier assignment of fluorenyl carbanion and carbazole nitranion.

Detection, Identification and Quantitative Analysis of Drugs by 1H NMR

1986
The application of high-resolution proton NMR spectroscopy to the measurement of drugs and their metabolites in biological fluids is of increasing interest to analytical chemists and toxicologists. Much of the pioneering work in this area has used very high magnetic field strengths (400 and 500 MHz).

1H NMR analysis of R-75-1 substance.

The Japanese journal of antibiotics, 1981
Compound R-75-1 is a very potent rifamycin derivative prepared from rifamycin SV at the Sichuan Institute of Antibiotics Industry, China in 1975. This compound showed a strong (see graphs in book) activity against Myobacterium tuberculosis and Gram-positive organisms. Here we describe the assignment of the 1H NMR spectrum of this novel compound.
