← ScienceWhich outcome occurs when excited electrons within a dye molecule return to their ground state configuration?
A)Photon emission at a specific wavelength✓
B)Increased molecular vibrational energy
C)Destructive interference of molecular orbitals
D)Formation of new covalent chemical bonds
💡 Explanation
When excited electrons transition back to the ground state configuration, spontaneous emission occurs because the energy difference between the excited and ground state orbitals is released as a photon with a specific wavelength. Therefore, light is emitted , rather than vibrational energy increase, orbital interference or covalent bonds, which need alternative stimuli.
