Far infrared laser magnetic resonance of singlet methylene: Singlet–triplet perturbations, singlet–triplet transitions, and the singlet–triplet splittinga)
We have observed and assigned a number of far infrared laser magnetic resonance spectra
of CH2 arising from rotational transitions within the lowest vibrational state of the a ̃ 1 A 1
electronic excited state and from transitions between such singlet levels and vibrationally
excited levels of the X ̃ 3 B 1 electronic ground state. The singlet–singlet transitions are
magnetically active, and the singlet–triplet transitions have electric dipole intensity because
of the spin‐orbit mixing of singlet levels with vibrationally excited levels of the triplet state. By …
