solution NMR is slightly different from solid state NMR.
the basic is relaxation depends not only on the dynamics/motion of the
molecules but also field depend.
Generally, small molecules have long relaxation time and high field will
reduce the relaxation time.
The linewith depends intrinsically on the chemical conformation, but also
depends on the external field.
so, it is always a compromise to select high or low field spectrometer.

比如这句，一看就是没有上过高中的人写的：
“在尺度合适的情况下，金属纳米结构吸引液体分子的能力，比金属分子之间的吸引力
更大，这种情况使得液体迅速在金属表面展开”
就算连WETTING是什么意思都不知道，也不至于写出这么没有常识的句子吧。
我想去看看英文是不是也写错了，结果找到了原文：
http://www.sciencedaily.com/releases/2009/06/090602112259.htm
“At a certain size, the metal nanostructures adhere more readily to the
liquid's molecules than the liquid's molecules adhere to each other,causing
the liquid to quickly spread out across the metal.”
果然英文是没有写错的。

quantum mechanics, and that's how to extract the data by fitting the IR
spectrum. And so, we consider both the rotational energy and vibrational
energy to be due to the quantum effect. This is completely different from the
classical picture for the rigid body. Hopefully that |
