Study of Molecular Oxygen by X-Ray Emission Spectroscopy (XES) (CAT#: STEM-ST-0275-WXH)

Introduction

Molecular oxygen (O2) is a diatomic molecule that is composed of two oxygen atoms held together by a covalent bond. Molecular oxygen is essential for life, as it is used for respiration by many organisms. It's also essential for fossil fuel combustion. Molecular oxygen is very chemically reactive, and tends to form oxides by reaction with other elements and compounds quite easily.

Principle

XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an incident X-ray photon is used to excite a core electron, which leads to the transition of the electron from the ground state to the excited state, and then the excited state of the electron decays with the emission of an X-ray photon in order to fill the core hole.

Applications

Used for the study of electronic structure and for the qualitative and quantitative analysis of substances.

Materials

• X-ray emission spectrometer
• X-ray generating equipment (X-ray tube)
