Abstract
LONDON. Royal Society, December 2.—T. M.. Lowry and W. R. C. Coode-Adams: Optical rotatory dispersion (Pt. 3). The rotatory dispersion of quartz in the infra-red, visible, and ultra-violet regions. Measurements of optical rotatory power of quartz were begun in 1908 with the view of testing, in the most drastic way possible, methods that were being developed for studying rotatory dispersion in organic compounds. Data are now given for the rotatory power at 20° C. of a column of quartz, 496-4735 mm. in length, over a range of wave-lengths from 25,170 Å.U. to 2263 Å.U. Observed rotations range from 450° to 101,332°, and rotations per mm. from 0.906° to 2O2.328°/mm. The latter can be expressed, over the entire range of wavelengths, by the formula—
