Descriptor English: Spectroscopy, Electron Energy-Loss
Descriptor Spanish: Espectroscopía de Pérdida de Energía de Electrones
Descriptor espectroscopia de pérdida de energía electrónica
Scope note: Técnica para el análisis de la composición química de las moléculas. Se bombardea una sustancia con ELECTRONES monocromáticos. Algunos de los electrones que atraviesan la muestra perderán energía tras ionizar la capa interna de átomos de la muestra. La pérdida de energía es dependiente del elemento. El análisis del espectro de la pérdida de energía revela la composición elemental de la muestra. La MICROSCOPIA ELECTRÓNICA DE TRANSMISIÓN POR FILTRACIÓN DE ENERGÍA es un tipo de espectroscopia de la pérdida de energía de los electrones, que se realiza con microscopios electrónicos especialmente equipados para analizar el espectro de la pérdida de energía.

RDF Unique Identifier: https://id.nlm.nih.gov/mesh/D046590
Scope note: A technique for analysis of the chemical composition of molecules. A substance is bombarded with monochromatic ELECTRONS. Some of the electrons passing through the specimen will lose energy when they ionize inner shell electrons of the atoms in the specimen. The energy loss is element dependent. Analysis of the energy loss spectrum reveals the elemental composition of a specimen. ENERGY-FILTERED TRANSMISSION ELECTRON MICROSCOPY is a type of electron energy loss spectroscopy carried out in electron microscopes specially outfitted to analyze the spectrum of electron energy loss.
