Investigation the Cation Complexation Macrocyclic Ethers using 13C NMR Spin--Lattice Dipolar Relaxation
2010/4/19
The binding constants (Ka) of [18]crown-6 ether with Na+ , K+, and Ba2+ thiocyanates were determined by 13C{1H} NMR spin--lattice dipolar relaxation time measurements. The observed relaxation times (T...
