Chem 351: Spectroscopic Methods

I) Spectrometric methods:

General introduction – the electromagnetic radiation (particle model & wave model)

– Absorption of radiation by atoms and molecules – Beers Law (Instrumental

dev., chemical dev. And Spectrom. Error) – Instrumentation (source of radiation,

monochromator, detector, … etc) – single-beam spectrometer vs. double-beam

spectrometer.

II) Molecular Spectrometric Methods:

Molecular Absorption Spectrometry (MAS) – Methods of Analysis and their applications

– Flow Injection Analysis (FIA) – FIA- Spectrometry and some applications –

Fluoremetery and Phosphorimetry – FIA - Fluoremetry – FIA-Chemiluminescence.

III) Atomic Spectrometric Methods:

Absorption, emission and fluorescence of radiation by atoms in vapor phase – types

of flames, burners and nebulizers – Atomic Emission Spectrometry (AES) – Hollowcathode

lamp – Single-beam vs. double-beam atomic absorption spectrometers –

Atomic Fluorescence Spectrometry (AES) – Inductively Coupled Plasma-Atomic

Emission Spectrometry (ICP-AES) – Arc Spark Emission Spectrography.
