Study Notes
Definition and Explanation
- Absorption is a process in which the energy of a photon is transferred to a molecule, atom, or ion.
- It involves the transfer of energy from electromagnetic radiation to matter.
Types of Absorption
- Atomic Absorption: occurs when the energy from electromagnetic radiation is absorbed by atoms, causing them to transition to a higher energy state.
- Molecular Absorption: occurs when the energy from electromagnetic radiation is absorbed by molecules, causing them to vibrate or rotate more vigorously.
- Ion Absorption: occurs when the energy from electromagnetic radiation is absorbed by ions, causing them to gain kinetic energy.
Factors Affecting Absorption
- Concentration: increased concentration of the absorbing species increases absorption.
- Path Length: increased path length of the radiation through the sample increases absorption.
- Temperature: increased temperature can increase or decrease absorption depending on the system.
- Pressure: increased pressure can increase or decrease absorption depending on the system.
Applications of Absorption
- Spectroscopy: absorption is used to analyze the composition and properties of substances.
- Dyes and Pigments: absorption is used to create colors and hues in materials.
- Lasers: absorption is used to create population inversions and amplify light.
- Climate Science: absorption of infrared radiation by greenhouse gases contributes to the greenhouse effect.
