Analytical Chemistry
Stretching refers to the vibrational motion of chemical bonds where the distance between atoms increases or decreases, typically during molecular vibrations. In the context of molecular spectroscopy, such as infrared and Raman spectroscopy, stretching vibrations play a crucial role in determining the energy levels of molecules and their corresponding spectroscopic signatures. This type of vibration can be categorized into symmetric and asymmetric stretching, which are essential for identifying functional groups in various compounds.
