我们发现,在磁等效自旋对中的单重态(S)和三重态(T)的种群之间的不平衡可以通过溶解动态核极化产生:在部分氘代乙醇((CD 3CH 2 OD)-C-13)中,这种T/S不平衡可以通过交叉弛豫转移到质子和耦合C-13的可观察的增强信号。
We show that an imbalance between the populations of singlet (S) and triplet (T) states in pairs of magnetically equivalent spins can be generated by dissolution dynamic nudear polarization: In partly deuterated ethanol ((CD3CH2OD)-C-13), this T/S imbalance can be transferred by cross-relaxation to observable, enhanced signals of protons and coupled C-13.
