摘要：

By dissolving compounds in hyperpolarized liquid Xe, we have successfully transferred the Xe-129 polarization to other spins in solution. We have observed signal enhancements of over 45 for H-1, and over 70 for C-13, compared to their thermal polarization signals at 200 K and 1.4 T. The lifetimes of the enhancements are on the order of 20 min. In addition, in dissolved toluene we have seen preferential enhancement of the ring protons over the methyl protons.
