A four-pulse version of the pulsed double electron electron resonance (DEER) experiment has been applied to a series of TEMPO diradicals with well-defined interradical distances ranging from 1.4 to 2.8 nm (see picture). The new pulse sequence allows broad distributions of electron-electron distances to be measured without dead-time artifacts.
脉冲双电子-电子共振（DEER）实验的四脉冲版本已应用于一系列具有明确自由基间距离（范围从1.4到2.8纳米，见图）的TEMPO双自由基。新的脉冲序列能够测量宽范围的电子-电子距离，且不存在死时间伪影。
