Absorption flattening in the optical spectra of liposome-entrapped substances.
Measuring optical spectra of chromophore molecules entrapped in liposomes can lead to considerable distortion because of absorption flattening. This phenomenon is analyzed theoretically, and it is shown that the deviation from the Beer-Lambert law becomes larger as the molar absorptivity of the chromophore increases and as the number of entrapped molecules becomes larger. The theoretical equati...
متن کاملInfrared absorption spectra of vinyl radicals isolated in solid Ne.
Irradiation of samples of solid Ne near 3.0 K containing ethene (C(2)H(4)) with vacuum ultraviolet radiation at 120 nm from synchrotron yielded new spectral lines at 3141.0, 2953.6, 2911.5, 1357.4, 677.1, 895.3, and 857.0 cm(-1). These features are assigned to alpha-CH stretching (nu(1)), CH(2) antisymmetric stretching (nu(2)), CH(2) symmetric stretching (nu(3)), CH(2)-bending (nu(5)), HCCH cis...
متن کاملAbsorption Spectra of Phytochrome Intermediates
Native phytochrome (124kdalton) was isolated from etiolated seedlings o f Avena sativa L. cv. Pirol (Baywa, Munich). From low temperature spectra (0 °C to — 165°C ) o f phytochrom e samples irradiated either with red or far-red light, spectra o f intermediates were calculated. Both absorption bands o f the phytochrome chromophore were reported. On the pathway P r i V r , native phytochrome does...
متن کاملOptical Absorption Spectra of Bipolarons
The absorption of large bipolarons is investigated using the path-integral method. The response of a bipolaron to an external electromagnetic field is derived in the framework of the memory function approach. The bipolaron optical absorption spectrum consists of a series of relatively narrow peaks. The peculiarities of the bipolaron optical absorption as a function of the frequency of the elect...
متن کاملModeling of phytochrome absorption spectra
Phytochromes constitute one of the six well-characterized families of photosensory proteins in Nature. From the viewpoint of computational modeling, however, phytochromes have been the subject of much fewer studies than most other families of photosensory proteins, which is likely a consequence of relevant high-resolution structural data becoming available only in recent years. In this work, hy...
