Short summary
In this work, we study the relaxivity of long-lived states (LLSs) excited across two to three CH2 groups in four different compounds and find that a commonly used polarising agent in dissolution dynamic nuclear polarization (d-DNP) does not enhance relaxation significantly. This result is important for the future implementation of d-DNP hyperpolarization of LLS.
