Pi bonds excitation photons
WebbMolecular electronic transitions take place when electrons in a molecule are excited from one energy level to a higher energy level. The energy change associated with this transition provides information on the structure of a molecule and determines many molecular properties such as colour.

WebbThis photochemical reaction is best understood in terms of molecular orbitals, orbital energy, and electron excitation. In cis-retinal, absorption of a photon promotes a p electron in the pi bond to a higher-energy orbital. This excitation "breaks" the pi component of the double bond and is temporarily converted into a single bond. the grace 3 in 1 travel systemtheatre glory racehorseWebbStudy with Quizlet and memorize flashcards containing terms like Q 14.44: High-resolution mass spectrometry is advantageous in determining what key feature of an unknown molecule?
