## Abstract __Erythro__ and __threo__ configurational assignments have been made for 11 β‐fluoro‐α‐amino acids or esters using the effect of complexation of the ammonium group by 18‐crown‐6 ether on the ^19^F NMR parameters. For the __erythro__ configurations, ^3^__J__(HF) increases and a high‐fiel

Gas phase complexes of a-amino acids with Cu' have been engendered in a plasma desorption ion source by bombarding a mixture of a-amino acids and cupric salts. The resulting adducts MCu' and the fragments that include copper were studied using a time-of-Ñight analyser. The main fragments result from
