The principles of ultraviolet photoelectron spectroscopy, its analytical aspects and, purpose of study are presented in Chapter One. A description of the instrumentation and experimental procedure in ultraviolet photoelectron spectroscopy is given in Chapter Two. Chapter Three is a report on the study of a number of carbonates by ultraviolet photoelectron spectroscopy aided by INDO MO calculations. Study of polymer (PTFE) degradation is detailed in Chapter Four. The various products evolved from the polymer degraded between 400°C and 500°C for homopolymers, copolymers and γ-ray irradiated polymers; the kinetics of the decomposition and effects of molecular weight, sample thickness and surface area are discussed. Decomposition of polymer by thermogravimetry reported in Chapter Five complements the study by ultraviolet photoelectron spectroscopy. Chapter Six describes the principles of, and the results obtained by, optoacoustic spectroscopy.
