Abstract

EPR signal and noise, calculated from first principles, are compared with measured values of signal and noise on an S-band (ca. 2.7 GHz) EPR spectrometer for which all relevant gains and losses have been measured. Agreement is within the uncertainty of the calculations and the measurements. The calculational model that provided the good agreement is used to suggest approaches to optimizing spectrometer design.

摘要

从第一性原理计算得出的电子顺磁共振（EPR）信号和噪声，与在一台S波段（约2.7吉赫兹）EPR光谱仪上测量的信号和噪声值进行了比较，该光谱仪的所有相关增益和损耗均已测量。两者的一致性在计算和测量的不确定度范围内。提供良好一致性的计算模型被用于提出优化光谱仪设计的方法。
