Long-range coupling between protons separated by four or more bonds has recently been observed for a number of compounds' and it appears that a near pl-zig-sag arrangement of the atoms concerned Is required. 2'3 We report here observation of coupling between the C-l and C-3 protons in isoquinollne R

## Abstract Longβrange ^13^C,H NMR coupling constants were measured in strychnine at 400 MHz by a method that employs selective excitation of individual ^13^C sites under decoupled conditions followed by polarization transfer to protons. The sensitivity was improved by performing eight simultaneous
The hydroxyl groups of-carbohydrates give well resolved proton magnetic resonanoes if exchange reactions can be suppressed. Usually this is the fact when the pure sugar is dissolved in dry dimotbyl sulfoxide-dg (l&SO) or better in mixtures. of DbiSG.and acetone-d6 I,21 . Under these conditions the
