POLYMER STRUCTURE AND CHARACTERIZATION
www.cof.orst.edumolecular weights, and their molecular con gurations and conformations. Polymers are random-coil molecules that can exist in a variety of lengths, con gurations, and conformations. We can learn much about polymer materials purely by theoretical analysis of their conformations. Many
Structural Isomers – Just how many structures can you …
www.cpp.eduConformations are the result of differences in a structure from rotation about single bonds. We will study conformations more in a later topic. C C R R R H H H The three front bonds can rotate around the carbon-carbon single bond, like spokes on a wheel or propeller blades on an airplane.
13.6 Interpreting Proton NMR Spectra
www.columbia.eduthe conformations. For example: Cyclohexane gives a single peak for its H atoms in NMR. Half of the time a single proton is axial and half of the time it is equatorial. The observed chemical shift is half way between the axial chemical shift and the equatorial chemical shift. Title: 13_06_13.html.ppt [Read-Only]
