Abstract
In rapid scan EPR the changing magnetic field creates a background signal with components at the scan frequency and its harmonics. The amplitude of the background signal increases with scan width and is more significant for weak EPR signals such as are obtained in the presence of magnetic field gradients. A procedure for distinguishing this background from the EPR signal is proposed, mathematically described, and tested for various experimental conditions.
摘要
在快速扫描电子顺磁共振（EPR）中，变化的磁场会产生一个背景信号，其成分包括扫描频率及其谐波。背景信号的幅度随扫描宽度增加，对于诸如在存在磁场梯度时获得的微弱EPR信号而言更为显著。本文提出了一种将此背景与EPR信号区分开来的方法，对其进行了数学描述，并在各种实验条件下进行了测试。
