Abstract
A simple theoretical model is used to suggest that the NCCH coupling constant, Jnh, has a dihedral angle dependence that can serve for estimating the angle Psi in peptides. Some experimental comparisons are made to test the model; they include a new measurement of Jnh in N-acetylglycine.
摘要
一个简单的理论模型被用来表明，NCCH耦合常数Jnh具有二面角依赖性，可用于估计肽中的Ψ角。进行了一些实验比较以测试该模型；其中包括对N-乙酰甘氨酸中Jnh的新测量。
