许多样品不能用电子顺磁共振(EPR)谱来研究，因为它们太大了，放不进光谱仪，太珍贵了，不能破坏性地取样进行研究。建立了一台EPR移动式通用表面探测仪(MICE)，也称为单边EPR光谱仪，用于研究这类样品。EPR鼠标通过将鼠标放在物体上，可以无损地记录任何大小物体的小区域的低频EPR(LFEPR)频谱。EPR鼠标的能力在画布上的顺磁性颜料、纸上的磁性墨水和陶瓷烛台上进行了演示。鼠标的移动特性将允许将光谱仪带到样品中，从而打开EPR光谱学的新应用。(C)2017 Elsevier Inc.保留所有权利。
Many samples cannot be studied by electron paramagnetic resonance (EPR) spectroscopy because they are too large to fit into the spectrometer and too precious to be destructively sampled for study. An EPR mobile universal surface explorer (MOUSE), also known as a unilateral EPR spectrometer, was constructed for studying this class of sample. The EPR MOUSE can nondestructively record a low frequency EPR (LFEPR) spectrum of a small region of any size object by placing the MOUSE against the object. The capabilities of the EPR MOUSE are demonstrated on paramagnetic paint pigments on canvas, magnetic ink on paper, and a ceramic candlestick. The mobile nature of the MOUSE will allow the spectrometer to be brought to the sample, thus opening new applications of EPR spectroscopy. (C) 2017 Elsevier Inc. All rights reserved.
