Изобретение относитс к измерению параметров взаимодействи между парамагнитными центрами радкоспектроскопическими методами и может быть испопьзовано при различных структурных физике химических исследовани х.The invention relates to the measurement of interaction parameters between paramagnetic centers by radospectroscopic methods and can be used in various structural physics of chemical research.
Известен способ измерени взаимодействи между парамагнитными центрами с использованием двойного электронэлектронного резонанса С A known method for measuring the interaction between paramagnetic centers using double electron resonance C
Однако данный способ не обеспечивает возможности плавной и жестко контролируемой частоты перестройки радиочастотных генераторов.However, this method does not provide the possibility of a smooth and tightly controlled frequency tuning of radio frequency generators.
Наиболее близким к предложенному вл етс способ измерени параметров взаимодействи между парамагнитными центра га, включающий помещение образца в пол ризующее магнитное поле и формирование сигнала спинового эха от двух групп парамагнитных центров, причин возбуждение первой группы парамагнитных центров осуществл етс путем воздействи на образец последовательности радиочастотных импульсов, а дл возбуждени второй группы парамагнитных центров используетс дополнительный радиочастотный импульс, подаваемый в одном из- интервалов последовательности радиочастотных импульсов С 2 .The closest to the proposed method is the measurement of interaction parameters between the paramagnetic center of a gas, including placing a sample in a polarizing magnetic field and generating a spin echo signal from two groups of paramagnetic centers, causing the first group of paramagnetic centers to be excited by acting on a sample of radio frequency pulses, and to excite the second group of paramagnetic centers, an additional radio frequency pulse is used, supplied in one of the Alov sequence of radio frequency pulses With 2.
Однако дл осуществлени известного способа необходим бимодальный резонатор , обе моды которого настраиваютс на зеемановские частоты обеих групп However, to implement the known method, a bimodal resonator is necessary, both modes of which are tuned to the Zeeman frequencies of both groups.
10 парамагнитных центров, взаимодействие которых изучаетс , а также Два отдельных радиочастотных генератора на этих частотах. Кроме того, необходимо, чтобы была обеспечена ;возможность плавной и 10 paramagnetic centers, the interaction of which is studied, as well as two separate radio frequency generators at these frequencies. In addition, it is necessary to ensure that the possibility of a smooth and
