    Description / Table of Contents: Abstract Изучено влияние состояния адсорбционного слоя на образование мономерных и димерних катион-радикалов (KP) бензола на цеолитах структуры ZSM-5. Показано, что удаление бензола сопровождается исчезновением наблюдаемых KP, которое ноит обратимый характер и происходит с сохранением центров их стабилизации.
    Notes: Abstract The effect of the state of adsorbed layers on the formation of monomeric and dimeric benzene cation-radicals (CR) on ZSM-5 zeolites has been studied. Removal of benzene is shown to be accompanied by disappearance of CR, which is reversible and takes place with preservation of the sites for their stabilization.

    ESR “in situ” studies of photostimulated formation of benzene cation-radicals over ZSM-5 zeolites (1992)

    Description / Table of Contents: Abstract Обнаружено фотостимулированное овразование стабилизированных катоион-радикалов бензола на цеолите ZSM-5. Нонизация бензола протекает по одноквантовому механизму, начиная с энергии квантов 2,8 эВ. Предполагается образование донорноакцепторных комплексов адсорбированных молекул бензола с сильными акцепторными центрами поверхности цеолита. Освешение в полосе переноса заряда сопровождается фотодиссоциацией этих комплексов и овразованием катион-радикалов бензола.
    Notes: Abstract Photostimulated formation of stabilized benzene cationradicals over ZSM-5 zeolite has been found. Benzene ionization follows a monophotonic mechanism starting from photon energy hν=2.8 eV. The formation of donor-acceptor complexes of adsorbed benzene molecules with strong accepting sites on zeolite is suggested. Irradiation within the charge-transfer band is accompanied by photodissociation of these complexes and generation of benzene cation radicals.

    Description / Table of Contents: Abstract Измерена энергия активации Ea выхода кислорода из керамики YBa2Cu3O7-δ для значений δ от 0 до 0,2. Показано, что в интервале δ от 0,006 до 0,15–0,18 кислород достаточно однороден и характеризуется Ea=(36±3) ккал/моль. Изучены температурные зависимости низкополевого сигнала ЭПР этих керамик на частоте 9,3 КГц вблизи Tc.
    Notes: Abstract The activation energy Ea of oxygen evolution from the YBa2Cu3O7−/gs ceramics has been measured for σ ranging from 0 to 0.2. In the σ range from 0.15 to 0.18 oxygen is fairly homogeneous and its evolution is characterized by Ea=(36±3) kcal/mol. Temperature dependence of a low-field ESR signal of the ceramics have been studied at a frequency of 9.3 KHz nearby TC.
