Abstract
Description
図3には、第1実施形態に係るNMR分光計システムの一例が示されている。
以下、図12を参照して、第2実施形態に係るNMRプローブ54Aの回路構成について説明する。第2実施形態に係るNMRプローブ54Aは、第1実施形態に係るNMRプローブ54と同様に、低周波核種用コイルとしてのLFコイル86と、高周波核種用コイルとしてのHF1次共振器88と、を含み、これらのコイルによってクライオ・クロスコイルが構成される。第2実施形態においては、HF(高周波核種)用の高周波を照射しながら、LF1(低周波核種)のNMR信号とLF2(低周波核種)のNMR信号を取得する。LF1の周波数はLF2の周波数よりも高いものとする。なお、第1実施形態に係る構成と同じ構成には、第1実施形態と同じ符号が付されている。
以下、図14を参照して、第3実施形態に係るNMRプローブ54Bの回路構成について説明する。第3実施形態に係るNMRプローブ54Bは、第1実施形態に係るNMRプローブ54と同様に、低周波核種用コイルとしてのLFコイル86と、高周波核種用コイルとしてのHF1次共振器88と、を含み、これらのコイルによってクライオ・クロスコイルが構成される。第3実施形態に係るNMRプローブ54Bは、LF(低周波核種)のNMR信号を取得するための構成と、HF(低周波核種)のNMR信号を取得するための構成と、を含む。なお、第1実施形態に係る構成と同じ構成には、第1実施形態と同じ符号が付されている。
以下、図16を参照して、第4実施形態に係るNMRプローブ54Cの回路構成について説明する。第4実施形態に係るNMRプローブ54Cは、第2実施形態と第3実施形態との組み合わせに相当する。なお、第1から第3実施形態に係る構成と同じ構成には、第1から第3実施形態と同じ符号が付されている。
