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

## Abstract Two‐bond ^13^C^13^C coupling constants are discussed on the basis of INDO‐SCPT calculations. The dependence of ^2^__J__(CC) on bond angle variation and on methyl substitution is evaluated, and it is shown that ^2^__J__(CC) depends linearly on the bond orbital __s__‐character product of
