Why triplet excited states have lower energy levels than singlet excited states?

Hi! this was super useful but, whats the difference between vibrational relaxation and internal conversion?

This video was meant to give just a basic introduction to the Jablonski diagram, so I did not go into great detail. The semi-quick answer to your question is that when a molecule absorbs light it can promote an electron to an excited state (higher energy level). Often this excited state is the singlet state, meaning the electron at a higher energy level is still paired to an electron at the ground state (one has an up-spin, the other a down-spin). For the excited electron to go back to the ground state the molecule must release energy. One way to do this is for the molecule to bend and stretch its bonds (vibrate). I am sure a search on molecular vibrations will give some informative animations of this. The intersystem crossing occurs when the excited electron is no longer paired to the ground state electron (they both have the same spin) and is referred to as the triplet state. The relaxation of an electron in the triplet state back to the ground state results in phosphorescence (glow-in-dark types of things). Hope this helps.

vibration relaxation happens within one of the singlet states. Internal conversion moves an electron between two singlet states
