1. The red color of is caused by electron transitions into an antibonding orbital. 2. In rovibronic coupling, electron transitions are simultaneously combined with both vibrational and rotational transitions. 3. Thus the " non-orange " photons are mostly being absorbed by the electron transitions . 4. Electron transitions cause the emission or absorption of electromagnetic radiation in the form of quantized units called photons.5. Electron transitions from these levels in doubly ionized oxygen give rise to the 500.7 nm line.6. I understand electron transitions releasing light but I'm struggling with objects that do not emit light themselves. 7. For example, some theoretical methods ( DFT ) may not be appropriate to solve magnetic coupling or electron transitions properties. 8. The term " forbidden " is slightly misleading, as the electron transitions causing them are not forbidden but highly improbable. 9. Spectral emission occurs when an electron transitions , or jumps, from a higher energy state to a lower energy state. 10. Non-bonding orbitals are often designated by the letter "'n "'in molecular orbital diagrams and electron transition notations.
