Vapour diffusion growth and characterisation of fully deuterated triglycine sulphate (ND_2CD_2COOD)_3D_2SO_4

摘要

A new vial-in-vial vapour diffusion method for growing single crystals of fully deuterated triglycine sulphate (TGS) has been developed. Single crystals of hydrogenous TGS were also grown for comparison purposes. The crystals have been characterised using x-ray diffraction and differential scanning calorimetry. The phase transition temperature was 334.0 + 0.5 K for fully deuterated TGS compared to 322.3 ± 0.3 K for hydrogenous TGS. These values compare well with the expected T_c.
