## Abstract The one‐ and two‐bond ^13^C isotope shifts, typically −1.5 to −2.5 ppb and −0.7 ppb respectively, in non‐cyclic aliphatic systems and up to −4.4 ppb and −1.0 ppb in glucose cause effects that need to be taken into account in the adaptive NMR spectral library‐based quantification of the

Apart from its well-known role in the prevention of scurvy, ascorbic acid (1, vitamin C) has been implicated in a number of diverse biological processes. For example, the monooxygenase, dopamine fl-hydroxylase, which catalyzes the hydroxylation of 3,4-dihydroxyphenylethylamine (dopamine) to noradren

## Abstract An analysis of the ^1^H and ^13^C spectra of 1‐azafluorene has been carried out using computer calculations and homo‐ and heteronuclear double resonance techniques. The ^4^__J__, ^5^__J__ and ^6^__J__ long‐range coupling constants of the 9‐CH~2~ group protons with the protons of the pyr
