Analysis of Inorganic Analytes Using Spectroscopic-Based Methods
What is spectroscopy analysis?
Interaction of matter with
Electromagnetic Radiation
A form of energy is described by both waves & particles
Spectrum
Obtain data from a
spectrometer
/ spectroscopic analysis
Electromagnetic radiation
Interactions
of matter with electromagnetic radiation
Absorption
From ground state (lower energy) to excited state (higher energy)
Emission
From excited sate to ground state
Properties
Shorter wavelenght, higher frequency
Describe light as a
wave
and a
particle
Quantum of energy
E = hν
Types of transitions
Microwaves
Infrared rays
Visible lights
Ultraviolet, UV rays
X-rays
Gamma rays
Examples of spectrometry methods
Atomic spectroscopy
Measurement of
wavelenght
Measurement of
Intensity of light
that is emitted or absorbed by free atoms
Molecular spectroscopy
Interactions of light with molecules
Absorption spectroscopy
Amount of analyte
present in light path
Identity
of the coumpound
Beer - Lambert's Law
Absorbance is linear to concentration
