Ir functional group ranges
WebDec 21, 2015 · Functional groups are structural units within organic compounds defined by specific atom and bond arrangements. Infrared is a powerful identification tool for functional groups because of the similar … WebA vibrational mode involves the whole molecule, although it tends to be localized mostly on a functional group. The C=C bond is symmetrical, but the rest of the molecule is attached to it, and the rest of the molecule is three-dimensional.
