Which mechanism explains why paramagnetic oxygen can stabilize triplet electronic states in organic molecules?

💡 Explanation

When paramagnetic oxygen interacts with an organic molecule, spin-orbit coupling increases because the oxygen's unpaired electrons perturb the molecule's electronic structure, enhancing the rate of intersystem crossing (ISC) to triplet states. Therefore, spin-orbit coupling inducing ISC enhancement causes triplet state generation, rather than singlet fission, energy transfer, or Pauli exclusion, which rely on different pathways or molecular proximity.
