conformations

and master conformation of alkanes, isomerism, cis-trans isomerism and enantiomorphism;

By cooperation with thiophene ring, which results in the better conformations, the absorption and emission spectra exhibit bathochrome. 7.

helix: A helical conformation of a polypeptide chain, usually right-handed, with maximal intrachain hydrogen bonding; one of the most common secondary structures in proteins.

The macroscopic conformation and microscopic structure of the straticulate dolostone and spatulate dolostone suggest that the dolostones formed in a highenergy environment;

For the reason why optical activity of mesomer is counteracted classical answer was not convincing. By use of the helix theory and stable staggered conformation answer can be obtained.

It was found that the compounds are adsorbed on the Ag surface through the carboxyl oxygen atoms, the benzene adopts acclivitous conformation, others lie low on the Ag surface.
