✦ Synopsis

The axial form of I5 N enriched aminocyclohexane has been detected at 173K, permitting the first direct measurement of the conformational free energy of the NH2 group. Relative intensities of individual conformer resonances in NMR spectra at low temperature, where ring inversion is estimates of the conformational free & For X = NH,, small differences

## Abstract The conformational properties of __cis__‐5,8,11,14‐eicosatetraenoylethanolamide (anandamide) were analysed by the combined use of NMR experimental results plus molecular simulations. The structure of anandamide was found to be a predominantly linear with a seven‐atom ring of the ethanol

We have measured the 27A1 nuclear magnetic resonance, NMR, spectra of oriented powder of the intermetallic compound CeaAlll at temperatures between 0.03 K and 20 K, and frequencies of 2.815 MHz, 3.925 MHz, 9.208 MHz and 74.81 MHz. In the paramagnetic state the NMR spectra show the quadrupolar-split
