Study Notes
Molecular Spectroscopy
- Molecular spectroscopy is a technique used to study the interaction between matter and electromagnetic radiation.
Information Provided by Molecular Spectroscopy
- Molecular spectroscopy provides information about the energy levels and electronic transitions of molecules.
- It provides information about the molecular structure, bonding, and chemical properties of molecules.
Types of Energy Levels in Diatomic Molecules
- The three types of energy levels in diatomic molecules are:
- Electronic energy levels: related to the energy of the electrons in the molecule.
- Vibrational energy levels: related to the vibrations of the atoms in the molecule.
- Rotational energy levels: related to the rotation of the molecule as a whole.
Changes in Molecular Spectroscopy
- The changes that can occur in molecular spectroscopy include:
- Electronic transitions: changes in the energy levels of the electrons in the molecule.
- Vibrational transitions: changes in the vibrational energy levels of the molecule.
- Rotational transitions: changes in the rotational energy levels of the molecule.
Examples of Absorption and Emission Spectra
- Absorption spectra: a spectrum that shows the wavelengths of light absorbed by a molecule.
- Emission spectra: a spectrum that shows the wavelengths of light emitted by a molecule.
- Examples of absorption and emission spectra include:
- The absorption spectrum of a molecule showing the wavelengths of light absorbed during electronic transitions.
- The emission spectrum of a molecule showing the wavelengths of light emitted during electronic transitions.
