Handbook of the Polariscope and Its Practical Applications
Excerpt from Handbook of the Polariscope and Its Practical Applications
The importance so long assigned to the property, possessed by many organic substances, of rotating the plane of polarization, alike in its theoretical and practical aspects, makes it rather surprising that hitherto the only help available for the study of the subject was to be found in the various memoirs, in which the necessary information lay scattered, in scientific journals. The present work was undertaken with a view to relieve the inconvenience arising from the want of a comprehensive treatise. It is based upon a paper of mine published some time ago in Liebig's Annalen, Bd. 189, in which I discussed the mode of determining specific rotation, and, by way of introduction, gave a brief general account of optical activity. Since then requests have frequently reached me, urging the desirability of extending that paper by including an account of all the recent instruments and the practical applications, so as to make it a complete monograph of the subject. I was the more readily induced to undertake the task by the fact that, of late years, the increased attention given to the phenomena of rotation has brought to light such a mass of facts as makes it possible to present the material in a more or less complete form.
In its theoretical aspect the optical activity of organic substances possesses high interest. As it is a consequence of peculiarity of arrangement of the atoms in the molecule, it must assuredly afford some assistance in determining the constitutional formula to be assigned to the substances. The investigation of this connection between optical power and chemical constitution is, indeed, of the utmost importance, and gives promise of a rich harvest for future workers.
