TABLE 1.

Spin-lattice relaxation values, and % polarization achieved for multi-compound polarization at 11.7T. T1’s and signal enhancements were similar to those observed when the individual compounds were polarized separately and dissolved in an identical 100mM pH 7.8 phosphate buffer. Standard deviations are reported (N=3).
