1H NMR signal enhancement by NOVEL DNP as a function of the length of the electron spin-locking pulse (mixing time). Each 1H NMR spectrum is an average of 128 acquisitions. Before each 1H NMR acquisition, polarization is built up by repeating the electron spin lock at the NOVEL condition at a 1 kHz rate for 2 s.
