High-resolution nuclear magnetic resonance spectra at 100 MHz have been obtained on poly-iV-methyl-L-alanine in the chloroform-trifluoroacetic acid system under various conditions of solvent composition. Different spectra are observed for the CH,-C,, C,-H, and N-CHI protons. On the basis of conforma

The N-oxide group of the cellulose solvent N-methylmorpholine-N-oxide showed a strong preference for the axial position compared with N-methyl as determined by NMR experiments and computational studies. In solvents with negligible solvent -solute interaction, about 95% of the NMMO molecules obtained

Using ab initio theoretical approaches, we investigated the relative stability of two of the possible isomers of N-phenylbenzohydroxamic acid, PhCONOHPh. In particular, within the framework of density functional theory (DFT), we studied the cis and trans conformational isomers of PhCONOHPh, both in
