The Modification And Use Of An Electron Paramagnetic Resonance Spectrometer For Data Collection At Liquid Nitrogen Temperature, Vernon Lee Baumberger

Electronic Theses and Dissertations

The scope of this study includes the modification of an EPR spectrometer for acquisition of low temperature data. The modification involved adaptation of the system for use with a cylindrical cavity specifically designed for low temperature operation. This modification increased the capability of the present system for data collection at liquid nitrogen temperature and gave such greater stability than the rectangular cavity previously used. A comparison was made of signal to noise for the two cavities. This study showed a somewhat greater signal to noise ratio for the low temperature cylindrical cavity. Operation at low temperature also allowed the observation …
