Proton resonance assignments in copolymer spectra by 2D NMR.
01 January 1984
Two-dimensional nuclear Overhauser effect (2D NOE) NMR has been employed to make assignments in the 200 MHz proton spectrum of a 65:35 (mol ratio) random free radical vinylidene chloride (V): isobutylene (I) copolymer. The principle of the method is based in the spatial proximity of the central methylene protons in tetrad comonomer sequences.
