硝酸铅魔角旋转 (MAS) 光谱中 (207)pb 化学位移的非常灵敏的温度依赖性为固态 NMR 测温提供了一种极好的方法。温度依赖性在至少-130至+150℃的范围内是均匀的，并且NMR灵敏度和线宽也非常有利。事实证明，硝酸铅可用于 MAS 探针来测量样品温度变化、温度梯度、MAS 热效应和温度跳跃动态。 (C) 1995 学术出版社
The remarkably sensitive temperature dependence of the (207)pb chemical shift in magic-angle-spinning (MAS) spectra of lead nitrate provides an excellent method for thermometry in solid-state NMR. The temperature dependence is uniform over a range of at least -130 to +150 degrees C, and also the NMR sensitivity and linewidth are very favorable. It is demonstrated that lead nitrate can be used in MAS probes to measure sample temperature changes, temperature gradients, MAS heating effects, and the dynamics of temperature jumps.
