## Abstract The NMR variable temperature behaviour of __N__‐aroyl‐ and __N__‐thioaroyl‐__N__′‐piperonylpiperazines was investigated. The largest chemical shift separation between the exchanging methylene groups, and the highest energy barrier, is found for the thioamide compounds. Results from semi

## Abstract ^1^H, ^13^C and ^15^N nuclear magnetic resonance studies of gold(III), palladium(II) and platinum(II) chloride complexes with phenylpyridines (PPY: 4‐phenylpyridine, 4ppy; 3‐phenylpyridine, 3ppy; and 2‐phenylpyridine, 2ppy) having the general formulae [Au(PPY)Cl~3~], __trans__‐/__cis__‐
## Abstract The high temperature ^13^C NMR spectra of the methyl esters of deuteroporphyrin‐IX and protoporphyrin‐IX, and octaethylporphyrin show sharp discrete signals for the inner macrocycle carbon resonances. The temperature dependence of these shifts is discussed.
## Abstract The ^1^H NMR spectra of imidazo [1,2‐__a__]pyrimidine derivatives have been analysed to study the aromatic character and protonation behaviour of this system. By employing the ‘ring currentn’ model and calculations based on the coupled Hartree‐Fock method it can be deduced that a large
## Abstract ^13^C NMR spectra of 27‐hydroxyfriedelane, kokoonol (27‐hydroxyfriedelan‐3‐one) and kokoononol (27‐hydroxyfriedelan‐3,21‐dione) have been recorded and signals assigned using the off‐resonance decoupling, inversion recovery and lanthanide induced shift techniques.
