Association of Mg²⁺ and La³⁺ ions with Reiсhardt betaine dyes in deuterated DMSO has been studied using ¹H-NMR method. Basing on chemical shifts of the betaine protons in the presence of metal ions as well as on the chemical shifts of the protonated betaine protons, the Mg²⁺ and La³⁺ ions interac...
