## Abstract The effects of an hydroxy substituent on ^13^C^13^C coupling constants and ^13^C chemical shifts have been measured in 1‐hydroxynaphthalene‐2‐^13^C and 1‐hydroxypyrene‐1‐^13^C. The changes observed in the ^13^C^13^C couplings show the effect of a substituent attached directly to the l

✦ Synopsis
Abstract
Long range inter‐ring ^13^C^13^C couplings are found to be effective in the title compounds, and the magnitudes of coupling constants and of substituent effects on ^13^C chemical shifts, as well as the signs of the latter, alternate with respect to the number of connecting bonds.

## Abstract The ^13^C^13^C spin–spin coupling constants in natural abundance oxetane, thietane, cyclobutanone, bromo‐and chlorocyclobutane have been measured. Furthermore, the ^13^C isotope‐induced changes in the chemical shifts of the different ^13^C nuclei in the molecules mentioned above are re
The attachment of an ester group at C-4 (1) and lactone bridges between C-6 and C-8 (1); C-2 and C-4, C-6 and C-8 (2); C-4 and C-6 (4) resulted in C-4, C-5 and C-6 showing similar chemical shifts in all three structures. In Diosbulbins A (1) and B (Z), C-12 bearing the equatorial furan ring is in an
## Abstract The synthesis of benzo[a]pyrene‐6‐^13^C is described. Perinaphthane was converted to 6‐benzoyl‐carbonyl‐^13^C‐perinaphthane which was cyclized to 2,3‐dihydrobenzo[a]pyren‐6(1H)‐one‐6‐^13^C. Subsequent reduction of the ketone followed by dehydration and dehydrogenation gave benzo[a]pyren
