新しい時間領域ESRを用いた，無定形試料中の磁性分子のナノ構造とナノダイナミクスに関する研究を解説した．また，電子スピン間相互作用である双極子・交換相互作用と電子スピン-核スピン間相互作用である核変調効果を概説し，時間領域ESRの原理についても簡単に言及した．

A growth of nanoscience requires spectroscopy which allows us to measure a nanometer scale with a high accuracy. Time-domain ESR spectroscopy has been recently developed to detect small exchange and dipolar interactions that are effective even between two spins with subnano or nano meter separations. This review focuses the advanced time-domain ESR spectroscopic studies on nanoscale structure and dynamics in amorphous or glassy samples.
