Bond lengths, quadrupole coupling constants, chemical shifts and vibrational frequencies are important probes of hydrogen bonding. This was previously demonstrated for liquid N-methylacetamide (NMA) showing that cooperativity and non-additive contributions of hydrogen bonds play a significant role.

This paper presents the synthesis and characterization by mass spectrometry and NMR spectroscopy of [2-13 C]-and [3-13 C]ubiquinone-0 and of [5-13 C]-and [6-13 C]ubiquinone-10. A scheme based on the synthetic approach to [5-13 C]ubiquinone-10 has been worked out for the synthesis of ubiquinones 13 C
