A study of long-lived spin states in hetero-nuclear spin systems is presented. Since long-lived states are efficiently sustained only when the spins are "strongly coupled", this study necessitates going to "ultralow" magnetic fields, which are much l

Photochemically induced dynamic nuclear polarization (photo-CIDNP) is a method to hyperpolarize nuclear spins using light. In most cases, CIDNP experiments are performed in high magnetic fields and the sample is irradiated by light inside a nuclear m
