✦ Synopsis

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 and is compared to that of umbellulone recorded earlier.

In aqueous solutions, 13C-and 'H-nmr studies show that the percentage of trans conformation of proline oligomers +H\*N Pro-(Pro),-CO; increases substantially from n = 1 (65% trans) t o n = 2 (90% trans). The relatively low percentage of trans structure for the dimer ( n = 1) very likely is caused by

## Abstract Carbon‐13 NMR spectra of solid polycrystalline bicyclo[3.3.1]nonan‐9‐one and adamantanone have been measured at 315K. The relatively narrow ^13^C linewidths observed for these solids, together with measured spin‐lattice relaxation times, indicate that both these solids are orientational
