OPTICAL PROPERTIES OF BIOPOLYMERS IN THE RANGE OF ELECTRON ABSORPTION BANDS
Abstract
In analyzing the main optical properties of polypeptides and nucleic acids attention was turned to the essence of the origin of effects in the area of absorption bands. Only the experimental results for long helical molecules were discussed. Certain problems which are secondary in respect to the main effects, such as the influence of the solvent or manifestation in transparent areas of the spectrum, were not touched upon, though they undoubtedly have great significance in analytical work. Nevertheless it is noted that an analysis of dispersion of rotation in the visible range may produce supplementary information in an analysis of a mixture of structural forms, though at the present time this interpretation bears an empirical nature to a considerable degree. A comparison of theory and experimental data for the area of absorption shows that there is qualitative agreement between them. In a quantitative comparison the problem arises of the accuracy of the spectral characteristics used during calculation on the one hand, and consideration of the contribution of various effects of a second order of smallness on the other.
