## Abstract All ^13^C—^13^C splittings involving the C‐4 carbon of 4‐propyl‐3‐heptene and the C‐1 carbon of 1‐methylcyclohexene were determined from the appropriately labeled (> 90%‐^13^C) derivatives. The observed trends in coupling constants continue to offer additional means of carbon chemical s
We propose the 13 C-detecting 1D DEPT long-range C-C relay to detect super long-range H-C connectivity via four bonds ( 1 H-13 C-X-X-13 C, X represents 12 C or heteronuclear). It is derived from the DEPT C-C relay which detects the H-C correlations via two bonds ( 1 H-13 C-13 C) by setting the delay
## Abstract Proton coupled ^13^C NMR spectra have been recorded for some acylphloroglucinol derivatives. Significant couplings over two, three and four bonds were observed between the hydroxyl proton and aromatic carbons for those compounds where the hydroxyl group is hydrogen bonded strongly enoug
