Magnetic dipole allowed excitations

Finally, it should be noted that L is a rotational operator. Therefore, any type of transition that involves exciting an electron between orbitals that are transformed into one another by a rotation (e.g., the n —> n transition of an inherently chiral carbonyl)20,21 will be magnetic dipole allowed and have g > 0.01. 

Allowed components of the excited states associated with the electronic transitions. Transitions to T4g are magnetic dipole allowed, transitions to r4u are electric dipole allowed... 

In the excitation spectra of the uranium-doped tungstates several broad uranate excitation bands are observed at room temperature. The lowest energy excitation band is ascribed to a 127gu 477 magnetic dipole allowed transition. The zero... 

The strong sharp line at 500.4 nm in the emission spectrum of Ba2MgW06—U is assigned to the zero-phonon line of the magnetic-dipole allowed component of the 7 u 7su transition within the octahedral uranate group (Table 4). At 499.4 run another relatively sharp line is observed (Fig. 8). Our selective excitation experiments reveal that this line is the zero-phonon line of the 7gu transition originating... 

Magnetic-dipole-allowed transitions between the spin doublets Fi(J) and p2(J) in the X Bi ground and the A Ai excited electronic states were observed in microwave optical double resonance (MODR) spectra in the frequency range<30 GHz (1 cm ). In addition, a few MODR bands were identified as electric-dipole-allowed transitions in the ground state X Bi which have three to four orders of magnitude stronger transition rates than the magnetic-dipole-allowed MW transitions [4].
