Hindered Rotation in Poly(N-acyl)iminoalkylenes - A 13C Nuclear Magnetic Resonance Study
Poly(N-acetyl)iminoethylene. poly(N-propionyl)iminoethylene and poly(N-acetyl)-2,2-dimethyliminoethylene were prepared by cationic polymerization in solution of 2-methyl2-oxazoline, 2-ethyl-2-oxazoline, and 2,4,4-trimethyl-2-oxazoline respectively. The 13C NMR spectra of the polymers obtained showed different sets of shifts for the carbon atoms of the backbone as well as for the N-acylimino sid...

متن کاملThe Effective Fragment Model for Solvation: Internal Rotation in Formamide
The internal rotation of formamide with 0–5 water molecules oriented along the N–C bond has been studied by the full ab initio self‐consistent field theory and using the effective fragment (EFP) method. For each case, the EFP geometries, harmonic vibrational frequencies, rotational barriers, and intrinsic reaction coordinates for the internal rotation are found to be in excellent agreement with...
