The Dobryakov–Lebedev relation (Sov Phys Doklady 13:873, 1969), which relates the line width of the first-derivative of a Gaussian–Lorentzian convolution to the line widths of its Gaussian and Lorentzian components for an unresolved EPR line, is extended to resolved lines. Applying this extension to nitroxide-free radicals in solutions of low-viscosity solvents offers an opportunity to study interactions of the spins with the microwave field and spin–spin interactions previously inaccessible except by tedious numerical methods.

Dobryakov-Lebedev 关系扩展到部分解析的 EPR 谱

Dobryakov-Lebedev 关系 (Sov Phys Doklady 13:873, 1969) 将高斯-洛伦兹卷积的一阶导数的线宽与未解析 EPR 线的高斯和洛伦兹分量的线宽联系起来解决线路。将此扩展应用于低粘度溶剂溶液中的氮氧自由基，提供了一个机会来研究自旋与微波场的相互作用以及以前除了繁琐的数值方法之外无法获得的自旋-自旋相互作用。
