## Abstract Analysis of the noise decoupled ^13^C spectra of doubly ^13^C labelled compounds where the two labelled carbons are identical, makes the determination of reltive signs of ^13^C^13^C coupling constants possible in a very simple way. The involved carbon form AA'X or AA'B spin systems.

An empirical projection method is described to predict the magnitudes and signs of two-bond 13C-13C spin-coupling constants (2Jcc) in aldopyranosyl rings. The method has been applied primarily to the interpretation of 2Jcc c values, although the behavior of 2Jco c has also been examined in light of
