  • Determination of the Rotameric Stability of 1,2-Dihaloethanes Using Infrared Spectroscopy. A Combined Experimental and Computational Project for the Physical Chemistry Laboratory

    Brian D. Wladkowski and Steven J. Broadwater
    Journal of Chemical Education 2002 79 (2), p 230

    Abstract:

    The effects of structure and environment on the rotameric energy difference between gauche and trans conformations of 1,2-disubstituted ethanes are determined quantitatively through the use of infrared spectroscopy. A series of three 1,2-dihaloethanes (...
