calculation. The steric repulsion still remains the most popular explanation of the hindered rotation of ethane. This effect is often understood as the increase in energy that accompanies ...
interactions. The multiple nonbonding forces hinder the internal rotation of benzene around the isopropyl CH bond in sevoflurane, producing detectable quantum tunneling effects in the rotational spectrum. ...

for the hindered internal rotation about the C–N bond , Earot, and for the intermolecular proton exchange involving the amine protons, Eaex, were obtained. It has been found that the hydrogen - bond formation ...
the short-time fast rotation is determined by the moment of inertia, the long-time rotation is affected by the interaction between fluid molecules and the zeolite atoms. In the case of water, hydrogen bonding ...
appear as benchmarks systems for investigating structural and dynamical effects associated with intramolecular hydrogen bonds . The multidimensional nature of the H int transfer process has been well ...
rotation within the thioamide functional group offers three differently populated conformers (Scheme 1).[3] While the mechanism for anion recognition or catalytic activation of a substrate due to hydrogen ...

by a polymethylene chain, new intramolecular unconventional N···H+···N hydrogen bonding effects were discovered. It is argued that the CH2—N rotation is hindered and two +H···NHCH3 non‐equivalent protons occur ...
Hydrogen bond (H‐ bond ) plays an important role in structure evolution and properties of various polymers. Due to directivity and saturation of H‐ bond , its formation is influenced by macromolecular ...
