Gas phase 13C chemical shifts and coupling constants in the deuteromethanes

Abstract

13C NMR shifts and coupling constants are reported for 13CH4, 13Cl4, and a mixture of 13CH4 and 13CH3D, 13CH2D2, 13CHD3 and 13CD4. The samples were prepared by reaction f 13CO with either pure H2 or a 1:1 H2:DD2.(AIP)
