Linear dependence of ¹J¹³C, ¹⁹⁹Hg) and ²J(¹H, C,¹⁹⁹Hg) for dibenzylmercury in various solvents

Abstract

The 1J(13C, 199Hg) spin–spin coupling constants have been studied for dibenzylmercury in various solvents. A linear correlation was found between 1J(13C, 199Hg) and the 2J(1H, C, 199Hg) constants obtained earlier for the same solutions.
