Cyclic radical cations Met-(S…︁█ N) of methionine could play an important role in processes such as long-range electron transfer across cell membranes and oxidative damage to cells. CIDNP spectroscopy (CIDNP = chemically induced dynamic nuclear polarization) furnishes direct structural proof and allows experimental investigation of the spin-density distribution in the two-center three-electron bonds.
甲硫氨酸的环状自由基阳离子Met-(S…︁█ N)可能在诸如跨细胞膜的长程电子转移和细胞氧化损伤等过程中发挥重要作用。CIDNP光谱学（CIDNP = 化学诱导动态核极化）提供了直接的结构证据，并允许对两中心三电子键中的自旋密度分布进行实验研究。
