摘要:

本文提出了一种基于行波谐振器的磁共振谱仪矢量分析方法,包括参考臂和频率的自动控制。所提出的模型,也适用于驻波谐振器,给出了任何工作条件下的光谱仪的响应函数,包括标量检测器与任意响应规律和任意激励频率。纯色散和纯吸收的线性响应进行了详细讨论不同的标量探测器。所开发的方法允许优化光谱仪的性能,并在非常宽的工作条件范围内获得样品的本征线形。更复杂的设置,可以模拟以下所提出的计划。

英文摘要:

A vectorial analysis of magnetic resonance spectrometers, based on traveling wave resonators and including the reference arm and the automatic control of frequency, has been developed. The proposed model, valid also for stationary wave resonators, gives the response function of the spectrometer for any working condition, including scalar detectors with arbitrary response law and arbitrary excitation frequency. The purely dispersive and purely absorptive linear responses are discussed in detail for different scalar detectors. The developed approach allows for optimizing the performances of the spectrometer and for obtaining the intrinsic lineshape of the sample in a very broad range of working conditions. More complex setups can be modeled following the proposed scheme.
