REFERENCE DATA causes the electron density to be comparatively lower at C-3 and C-5 than at C-2 and C-4, so that the former signals resonate at lower fields. Distinction between the signals of the C-2/C-4 and C-3/C-5 pairs was achieved by comparing the C-H coupling patterns of 5 and 1. Compounds 1,

## Abstract Fourier transform carbon‐13 nuclear magnetic resonance spectra have been obtained and interpreted for some 2‐substituted tetrahydropyrans. The effects of the substituents on α, β, γ and δ‐carbon atoms are discussed. Using suitable reference compounds the γ‐parameter can be used for quan

## Abstract The ^13^C NMR spectra were determined and signals assigned to the various carbons of the alkamines veracevine, germine and zygacine derived from steroidal alkaloids of the ceveratrum class. Assignment of signals was aided by analysis of the partially relaxed spectrum of cervagenine 9,12
## Abstract The ^13^C NMR spectra of methyl farnesoate and related compounds, including juvenile hormone III, are presented, as well as those of analogous compounds derived from methyl geranate. Correlations between the homologous derivatives are discussed in terms of substituent influences.
