Abstract (2. Language): 
In this study, complexation of crown ether (N,N’-Dioktil-7,16-diaza-1,4,10,13- tetraoksa-2,3,-benzosiklo oktadek-2-ene) doped with sodium ion was investigated by NMR relaxation time (T1) measurements. T1 values of the crown ether were measured with increasing concentration of NaClO4. Data show that 1/T1 increases with concentration and then remains constant. Constant values of 1/T1 after 1:1 crown ether-ion concentration were attributed to the binding of the crown ether with sodium ion.

Abstract (Original Language): 
Bu çalışma, NMR T1 ölçümleri yoluyla, taç eter (N,N’-Dioktil-7,16-diaza- 1,4,10,13-tetraoksa-2,3,-benzosiklo oktadek-2-ene) ile Sodyum iyonunun kompleksleşmesini incelemek amacıyla gerçekleştirildi. Taç eter çözeltisinin artan sodyum iyonu konsantrasyonuna karşı T1 değerleri ölçüldü ve grafiğe geçirildi. Grafiklerden 1/T1’in, 1:1 kompleksleşmesine kadar arttığı ve sonra da sabit kaldığı gözlenmiştir. Grafiklerdeki 1/T1 değerinin belli bir konsantrasyondan sonra sabit kalması bağlanmanın bir göstergesidir.
