Optical Rotatory Dispersion and the Twist Conformation of Cyclohexanones.
The Octant Rule1 provides a theoretical basis for the study of optical rotatory dispersion curves of ketones. The application of this rule to extensive collections of data for cyclohexanone types from our two laboratories has been described elsewhere.2 3 Among the hundreds of curves recorded, a few stand out by reason of their unusually large amplitudes (positive or negative), which cannot be r...

The application of optical rot,atory dispersion to nucleic acids and polynucleotides is fairly recent (l-6). Doty et cd. (2) made a comprehensive study of the optical rotatory dispersion of deoxyribonucleic acid, ribonucleic acid, and complexes of some homopolynucleotides; their results strongly suggested a close relationship between the optical rotations and the secondary structure of nucleic ...

The crucial test regarding the usefulness of the optical rotatory dtspersion method for the study of protein conformation was in confronting the results of this method w&the x-ray structural analysis of myoglobm. The high resolution x-ray structural analysis of Kendrew et al. on myoglobin crystals (1) and the optical rotation studies of Beychok and Blout (2) and Urnes, Imahori, and Doty (3) on ...
متن کاملQuantum optical rotatory dispersion
The phenomenon of molecular optical activity manifests itself as the rotation of the plane of linear polarization when light passes through chiral media. Measurements of optical activity and its wavelength dependence, that is, optical rotatory dispersion, can reveal information about intricate properties of molecules, such as the three-dimensional arrangement of atoms comprising a molecule. Giv...
متن کاملOptical Rotatory Dispersion of Catalase.
It is well recognized that the measurements of optical rotatory dispersion of proteins with strong absorption bands are extremely difficult because of the diminishing intensity of the emergent light. Until very recently, these studies were made possible only by improving the light source and also frequently by a wide opening of the slit width on the monochromator at the expense of spectral puri...
