## Abstract The carbon‐13 spectra of seventeen bicyclo[3.1.1]‐heptane derivatives have been recorded and assigned. Study of the C‐6 and C‐7 chemical shifts permits the conformations to be assigned to the bridged chair, Y‐shaped, or bridged boat conformations. The spectrum of verbenone is anomalous

Abstract
The ^1^H and ^13^C NMR resonances of 22 5‐(5‐substituted‐2‐nitrophenyl)‐1__H__‐pyrrole‐2‐carboxamides, 22 5‐(5‐substituted‐2‐aminophenyl)‐1__H__‐pyrrole‐2‐carboxamides, and 9 5‐phenyl‐1__H__‐pyrrole‐2‐carboxamides were assigned completely using the concerted application of one‐ and two‐dimensional experiments (DEPT, gs‐HMQC and gs‐HMBC). NOE studies and conformational analysis confirm the preferred conformations of such compounds. Copyright © 2009 John Wiley & Sons, Ltd.

The conformations of cysteamine, thiazolidine, and thiazolidine-4-carboxylic acid were determined in aqueous solutions using NMR spectroscopy. At physiological pH, the population ratio of gauche- and trans-conformers was 3:1. The gauche-rotamer is probably responsible for the antiradiation activity
## Abstract The ^13^C chemical shift of the substituted or functionalized carbon of various medium and large rings is plotted against ring size (6–15 carbons). The curves thus obtained allow a conformational analysis of the corresponding derivatives.
