Changes in intensity of some IR and Raman bands suggest the plasticizing – antiplasticizing effects of water and glycerol contents and a small increase of amorphous/crystalline ratio, too. The nuclear magnetic relaxation data show that the amorphou

The influences of starch, glycerol and water ratios on the structure, morphology and dynamics of starch polymer chains were investigated by NMR relaxation method. The 1 H NMR CPMG echo decays and saturation recovery build-up curves were recorded and

IR spectra changes of the x V 2 O 5 (1 − x )[0.8P 2 O 5 ⋅0.2Bi 2 O 3 ] glass system with 0 ⩽ x ⩽ 50 mol% show that vanadium oxide acts as a network modifier at low concentration ( x ⩽ 5 mol%), affecting especially the Bi 2 O 3 network. In t

The changes observed in the IR and ESR spectra of the xV 2 O 5 (1 − x)[0.8P 2 O 5 ∙ 0.2BaO] glass system with 0 ≤ x ≤ 50 mol% show that vanadium oxide acts as a network modifier at low concentration (x ≤ 5 mol%) and as a network former for

[ 15 N]-labelled lysine and ornithine amino acids together with their copper(II) complexes are investigated by IR and ESR spectroscopies. The small isotopic shifts in the vibrations frequencies of the bonds involving the N atoms were evidenced by com

IR, Raman and surface-enhanced Raman scattering (SERS) spectra of pindolol (PIN) and verapamil (VER) were recorded, and the vibrational bands were assigned on the basis of density functional theory (DFT) calculations. The adsorption geometry to the s

Thermoluminescence and optically stimulated luminescence properties of phosphate glasses doped with BaO and Li2O at various concentrations were studied. Lithium-doped glasses show a broad TL peak in the 200–300 °C region with poor dosimetric chara
