Abstract

Magnetic circular dichroism can detect the presence of certain special marker molecules in systems which contain overlapping absorption bands due to several other chromophores. The magnetic CD (MCD) of a marker molecule is relatively insensitive to the molecule's environment, in contrast to natural CD which may be due entirely to asymmetric molecular environments. To qualify as an MCD marker, a molecule must possess degenerate or nearly degenerate transitions. Thus MCD markers will often be excellent CD reporter groups also. The ultraviolet absorption bands of spinach ferredoxin illustrate these concepts.
