Ultraviolet photo electron spectroscopy

We can use Ultraviolet Photo Electron Spectroscopy (UPES) and Auger Electron Spec-troscopy (AES). UPES will give us information about chemical shift and finger print, and AES will give us finger print information.

Derivitization reactions have previously been employed to extend the sensitivity and resolution of IR, ultraviolet and X-ray photo-electron spectroscopy (7-13). Yet no proposed method has the range to accommodate the major oxidation products from polyolefins. As part of an ongoing study of polymer oxidation and stabilization, we discuss here a series of reactions with small, reactive gas molecules. The products from these reactions can be rapidly identified and quantified by IR. Some of these reactions are new, others have already been described in the literature, although their products have not always been fully identified.
