Transcription of Vibrational and Rotational Spectroscopy of Diatomic Molecules
{{id}} {{{paragraph}}}
Vibrational and Rotational Spectroscopy of Diatomic MoleculesSpectroscopy is an important tool in the study of atoms and Molecules , giving us an understandingof their quantized energy levels. These energy levels can only be solved for analytically in the caseof the hydrogen atom; for more complex Molecules we must use approximation methods to derivea model for the energy levels of the system. In this paper we will examine the vibration-rotationspectrum of a Diatomic molecule, which can be approximated by modeling vibrations as a harmonicoscillator and rotations as a rigid rotor.
Spectroscopy is the study of how matter interacts with electromagnetic radiation. Atoms and molecules inter-acting with light will sometimes emit photons at speci c frequencies; these frequencies depend on the energy level separation for whatever transitions caused the photon emission. We can use this to learn about the energy levels
