Infrared Spectroscopy and Nuclear Magnetic Resonance (NMR) Spectroscopy

To determine the appearance and disappearance of different functional groups, infrared spectroscopy and nuclear magnetic resonance (NMR) spectroscopy were used [2].

How this research used infrared spectroscopy and NMR

graphs of infrared spectroscopy and nmr readouts of polymers and blends
a. NMR spectra of the components, combinations and final formulation. b. NMR spectra of malic acid, selected reaction products and soy-mal-tan. (Diethyl malate is provided for an ester reference.) c. Infrared spectra of the carbonyl (C=O) region. d, Infrared spectra of the acid (CO–OH) region. [2]

Differential Scanning Calorimetry (DSC)

In order to determine the glass transition temperature of each material, differential scanning calorimetry (DSC) was used.
