本文介绍了一种连续波、零差、低频电子顺磁共振谱仪，它能测量直径为15厘米的物体。光谱仪可以利用在100和500 MHz之间操作的小体积和表面线圈探头。磁场可以在0和35 mT之间扫描，因此适合于< 2自旋和宽吸收线。光谱仪可以记录常规的场扫描、场循环和空间分辨光谱。详细介绍了仪器设计和六种不同样品的代表性光谱。该设计可应用于研究具有文化遗产意义的对象。
A continuous wave, homodyne, low frequency electron paramagnetic resonance spectrometer is described which can accommodate 15 cm diameter objects. The spectrometer can utilize small volume and surface coil probes operating between 100 and 500 MHz. The magnetic field can be scanned between 0 and 35 mT and is thus suitable forg< 2 spins and wide absorption lines. The spectrometer can record conventional field swept, field cycled, and spatially resolved spectra. Details of the instrument design and representative spectra from six different samples are presented. This design has applications to study objects with cultural heritage significance.
