Raman spectroscopy provides information about molecular vibrations

which are sensitive to interactions and conformations of the molecules. It enables the physicochemical features of polymers to be examined without resorting to chemical labeling and affords minimum sample preparation. Moreover

its spatial resolution can be better than 1 μm the lateral plane by focusing laser beams on the samples. Therefore

the construction unit

steric configuration

crystalline structure and conformational structure of the polymer chain can be studied by the Raman spectroscopy. Such as the Surface- enhanced Raman Scattering (SERS)

Variable temperature Raman spectroscopy

Confocal Raman Microscopy (CRM)

Raman Mapping and Resonance Raman scattering (RRS) are widely used in physics

chemistry and biomedicine. In this review

we summarize the research progresses of chain conformation

crystalline behave

chain diffusion and phase structure of polymer based on Raman technique

and deeply attempt to explore the applications of Raman spectroscopy in the polymer.
