Molecular spins clock in

Electron spin relaxation, important in quantum information science, can be slowed down at clock transitions — which are insensitive to magnetic noise. It has now been shown that such transitions can be tuned, to high frequency, in rare-earth coordination complexes through control of s- and d-orbital mixing.
