Glycine provided to research laboratories by chemical companies can contain different polymorphs and/or mixture of polymorphs. The alpha- and gamma-glycine differ slightly in 13C shielding parameters and very much in dynamic properties. The isotropic values of chemical shifts for carboxyl groups of
13 C NMR CP MAS data for three glycosyl a-tocopherol derivatives are reported. The values of D s d y d solution solid state provided information about rigid and conformationally flexible fragments of a-tocopherol molecule and the sugar moieties.
## Abstract The ^13^C NMR spectra of a series of dialkyl α‐anilinobenzylphosphonates and dialkyl α‐anilino‐(2‐hydroxybenzyl)phosphonates were measured. The assignment of the spectra was performed using a combination of ^31^P‐^13^C and ^13^C‐^1^H coupling constants and substituent‐induced chemical s
