Proceedings of the Indian Academy of Sciences - Section A Aims and scope Submit manuscript

Summary

  1. 1.

    The rotatory dispersion ofd- andl-camphorcarboxylic acids in 8 solvents is described. The dispersion is simple and obeys the one-term Drude equation.

  2. 2.

    The effect of solvents on the rotatory power is discussed.

  3. 3.

    The effect of constitution on rotatory power of camphorcarboxylic acid is also discussed.

  4. 4.

    Thed- andl-forms give identical rotation within the limits of experimental error and thus support Pasteur's Law of Molecular Dissymmetry.

  5. 5.

    The formula for the complex dispersion ofd- andl-camphors in ethyl alcohol has been recalculated. The simple rotatory dispersion formulæ forl-borneol in ethyl alcohol and benzene have also been calculated.
