Electron spin density matching for cross-effect dynamic nuclear polarization.

Yuanxin Li1, Asif Equbal, Kan Tagami, Songi Han.   

Abstract

A new design principle for a mixed broad (TEMPO) and narrow (Trityl) line radical to boost the dynamic nuclear polarization efficiency is electron spin density matching, suggesting a polarizing agent of one Trityl tethered to at least two TEMPO moieties.
