Carminomycins II and III, the main components of the carminomycin complex were isolated in pure state. Their crystalline exalates and acetate of cardminomycin II were prepared. The PMR spectra of both carminomycins and the 13C-NMR spectra of the oxalates were obtained. The molecular weights of the antibiotics were determined by mass-spectrometry. On the basis of the PMR spectra it was shown that carminomycins II and III had similar structures and differed in the stereoisomerism of the nitrogen-free fragment linked to the amino sugar. This was confirmed by the 13C-NMR spectra. The above fragment (C7H15O3) is analogous to the fragment of baumycins A1 and A2 described earlier.

D004578 Electron Spin Resonance Spectroscopy A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.
