Study Notes
Spectroscopy Overview
- Spectroscopy studies the absorption and emission of light and other radiation by matter.
- It provides information about the electronic, vibrational, and rotational energy levels in atoms and molecules.
Atomic Absorption Spectroscopy (AAS)
- AAS is a method that uses the absorption of light to determine the concentration of particular metals in a sample.
- It involves atomizing the sample and measuring the absorption of specific wavelengths of light.
Basic Types of Spectroscopy
- Three basic types of spectroscopy include:
- Absorption Spectroscopy: Measures the absorption of light as it passes through a sample.
- Emission Spectroscopy: Analyzes light emitted by excited atoms or molecules.
- Fluorescence Spectroscopy: Examines light emitted by a substance that has absorbed light or other electromagnetic radiation.
Electromagnetic Radiation
- Electromagnetic radiation, such as light, is described in terms of waves and particles.
- It exhibits behavior characterized by its wavelength, frequency, and energy, which are interrelated.
Purpose of Spectroscopic Methods
- The main purpose of spectroscopic methods in analytical chemistry is to identify and quantify the chemical substances in a sample.
- These methods offer insights into the composition and structure of materials through spectral data analysis.
