Circular dichorism

The interaction of TPPTS with p-CD has been investigated in detail by uv-vis, circular dichorism, and NMR and electrospray mass spectroscopy [4,5]. The main conclusion of these studies is that one of the... 

In order to find a more reliable indicator of Co(III)-azophenolate coordination in proteins, the circular dichoric properties of the models were examined. Initially an essentially empirical approach was taken. In the visible absorption spectra of the Co(III)-azophenolate complexes, the ligand associated transitions dominate the spectrum since the molar absorptivities of 4000 - 10,000 are at least an order of magnitude more intense than the configurationally forbidden d-d transitions, Figure 5.
