Abstract
From the study of the ^1^H n.m.r. spectral parameters of differently functionalized 1,4‐diacetoxy‐2,3‐dialkylcyclopentanes it is shown that the magnitude of those parameters allows an easy configurational assignment within a set of four different configurations.

## Abstract The configuration of some 1,4‐dihydroxy‐2,3‐dialkylcyclopentanes is assigned on the base of their ^1^H‐NMR spectral parameters. The interaction of the hydroxyl group with some side chains is discussed. It is shown that the magnitude of the ^1^H‐NMR spectral parameters of specific hydrog
## Abstract The preferred conformations of the four isomers of 1,2,3,4,4a,6,7,8,9,13b‐decahydro‐9a__H__‐pyrido[1,2‐__f__] phenanthridine have been determined by 270 MHz ^1^H n.m.r. and i.r. spectroscopy. N.m.r. assignments are based on the specific chemical shifts of the protons adjacent to the nit
