Experimental Techniques

Abstract

The experimental problems connected with LD measurements are generally much more complicated than those involved in ordinary MCD spectroscopy. The main reason is the need in LD studies for oriented molecular samples. MCD spectra can be obtained on commercially available instruments from liquid solutions in suitable solvents of the molecules to be investigated (9). Special applications of the MCD technique such as measurements on oriented samples are presently being attempted (10) and the theoretical basis for the orientational effects in such experiments has been worked out (11). An application with obvious analytical aspects (such as identification of compounds in very low concentrations) is fluorescence MCD, which has only recently been attempted experimentally, and for which some theoretical studies have been made (12).
