Abstract
^13^C NMR chemical shifts are reported for 1,2‐dimethoxybenzene (veratrole) and related benzodioxane, benzodioxepane and benzodioxenane systems and their 4‐nitro derivatives in solution and in the solid state. Results are discussed in terms of the stereoelectronic influence of substituents.

The 400 MHz t H and 15 MHz 13 C N MR spectra of a series of 2,4-diphenylquinoline derivatives are presented. The characteristic H-3 and ipso-phenyl carbon signals are the most useful for the identification of these compounds. The effects of a peri-phenyl/methyl couple upon the ~ H and 13C NMR spectr
17O, 13C and 1H NMR spectra for paraand meta-substituted 4-arylaminopent-3-en-2-ones (acyclic enaminones, 1 and 2) and 3-arylaminocyclohex-2-en-1-ones (cyclic enaminones, 3 and 4) are reported. The 17O, 13C and 1H shift values of these enaminones correlate well with and constants in the correlations
## Abstract The ^13^C spectra of α‐thujene (**1**), isothujone (**2**), (−)isothujol (**3**), (+)neoisothujol (**4**), sabinol (**5**), dihydroumbellulone (**6**) and umbellulone (**7**) and the alcohol acetates are recorded and assigned. The C‐6 chemical shift may be used in conjunction with the s
