Determination of Conformational Composition of Polyethylene Glycols by Raman Scattering and Quantum-chemical Calculations
2024
Kozlova, L. | Novikov, V.
This work is devoted to determining the conformational composition of a polyethyleneglycol sample with a molecular weight of 400 Da. For this purpose, experimental measurements of Raman spectra were performed, as well as quantum-chemical calculations of spectral lines in the non-proprietary Priroda software for PEG molecules with 9 monomer units of EG, which corresponds to the experimental sample in molecular weight. The calculated data for the 7/2 helical conformation showed a good agreement with the experiment.
