Abstract

The recently introduced method of detection of electron spin packet lines using double modulation technique has been examined in more detail in order to gain knowledge of its characteristics prior to applications. The theoretical explanation is given for the origin of the double modulation ESR spectrum and previous theoretical treatments are complemented and corrected. The experiments were carried out on irradiated single crystals of tryptamine hydrochloride, malonic acid and succinic acid. The spin packet line intensity exhibitis pronounced saturation behaviour beyond a certain power level. Below the saturation power level the line width is constant and increases rapidly at higher microwave power. Temperature studies have revealed that the parameters characterizing the spin packet lines are highly temperature dependent. Hence double modulation technique opens new perspectives in the studies of the molecular and crystal dynamics.
