Directed energy transfer due to orientational broadenning of energy levels in photosynthetic pigment solutions
(1982)
The directed non-radiative energy transfer through monomeric molecules of chlorophyll “a” and pheophytin “a” at high concentrations (c ~ 10⁻²) in a rigid matrix of polyvinylbutyral has been found by using the nanosecond ...
NH-Tautomerism and Visible Absorption Spectra of Porphyrins with Nonsymmetrical substitution
(1985)
On the basis or experiments Ihe oscillator model has been established for individual NH tautomers or porphyrins with asymmetrical substitution. CNDO/2 calculations explain the inversion of Q ₓ (O.O) and Q y (O.O) electronic ...
Radiationless intermolecular energy transfer with participation of acceptor excited triplet states
(1982)
Radiationless energy transfer between like and unlike molecules has been experimentally studied under conditions where acceptor molecules have been excited to the triplet state. Homogeneous singlet—triplet—triplet migration ...
Spectral Рeculiarities of NH-Tautomerism in Isocycle-Containing Porphyrins and their Covalently Linked Dimers
(1984)
It has been found experimentally that a whole class of isocycle-containing porphyrins, including synthetic and natural objects and their covalently linked dimers, shows NH-tautomerism which manifests itself in isotropic ...
Метод расчета интенсивности линий и изменения геометрии молекулы при резонансном комбинационном рассеянии
(Наука и техника, 1984)
Аналитически получены формулы для вычисления безразмерных сдвигов равновесных межъядерных расстояний и интенсивностей высших возбуждений и составных частот в спектрах резонансного комбинационного рассеяния с учетом точного ...
Плотность состояний на поверхности твердого тела с примесью замещения
(Наука и техника, 1985)
Аналитически вычислена плотность одночастичных состояний в примесной зоне случайно распределенных адатомов в узлах некоторой двумерной решетки.
