Off-the-Shelf Gd(NO3)3 as an Efficient High-Spin Metal Ion Polarizing Agent for Magic Angle Spinning Dynamic Nuclear Polarisation

I present work from @DrFredericBlanc's group at @LivUni (@StuartJElliott1, @BenDuff15, Ashlea Taylor-Hughes, and myself, plus collaborators at @ENSdeLyon, @UniofNottingham and @OfficialUoM) on the use of Gd(NO3)3 as an accessible, affordable DNP polarising agent. #GlobalnmrTC2023 pic.twitter.com/nef96W8aNs

Paramagnetic metal ion complexes have been demonstrated as an alternative to traditionally-used biradical polarising agents for DNP, which are typically not commercially available. Based on this, we have introduced Gd(NO3)3 as an easily accessible and inexpensive “off-the-shelf” polarising agent, providing significant sensitivity enhancements for 13C and 15N.
