    Description / Table of Contents: Abstract Фотоадсторбция кислорода в области примесного поглощения рутила зависит от степени гидратации поверхности, а максимум активности расположен вобласти собственного поглощения. Фотоадсорбция CO наблюдается в области собственного поглощения.
    Notes: Abstract Oxygen photoadsorption in the range of impurity absorption of rutile is governed by the surface hydration. The activity maximum is in the region of intrinsic absorption, where carbon monoxide is photoadsorbed.

    Description / Table of Contents: Abstract В области собственного поглощения рутила реакция окисления CO протекает по окислительновосстановительному механизму через взаимодействие CO с ион-радикалами O−, причём фотокаталитическая активность определяется плотностью 2р-состяний у потолка валентной зоны.
    Notes: Abstract In the region of intrinsic rutile adsorption, CO oxidation follows a redox mechanism via the interaction of CO with O− ion-radicals, and the photocatalytic activity is determined by the density of 2p states close to the top of the valence band.

    Description / Table of Contents: Abstract Изучены свойства парамагнитных центров, специфичных для восстановленного анатаза: $$\boxed{O^ - }$$ (g1=1,999, g2=1,984, g3=1,979) и $$\boxed{O_3^ - }$$ (g1=2,046, g2=2,008), связанных со стабилизацией фотоиндуцированных дырок вблизи анионных вакансий. На восстановленном окисле обнаружен новый тип фотоадсорбции O2 при hν〉1 эв, связанный с генерацией на поверхности только электронных центров.
    Notes: Abstract The paramagnetic centers of reduced anatase $$\boxed{O^ - }$$ (g1=1.999, g2=1.984, g3=1.979) and $$\boxed{O_3^ - }$$ (g1=2.046, g2=2.008), assigned to the stabilization of photoinduced holes near anion vacancies, have been studied. For the reduced oxide a new type of O2 photoadsorption at h ν〉1 eV due to the generation of only electron surface centers has been discovered.

    Description / Table of Contents: Abstract Методом ЭПР показано, что низкотемпературное фотовосстановление анатаза в CO имеет место как в области собственного, так и примесного поглощения окисла и сопровождается образованием анионных вакансий. Последующее облучение в присутствии O2 приводит к образованию кислородных комплексов O 3 − , связанных с наличием анионных вакансий.
    Notes: Abstract ESR studies show taht the low temperature photoreduction of anatase in CO proceeds in both the fundamental and impurity light absorption regions of the oxide, leading to anion vacancies. Further irradiation in the presence of O2 leads to $$\boxed{O_3^ - }$$ complexes, assigned to anion vacancies.
