The presence of NO can be detected by circular dichroism (CD) spectroscopy, which is based on an asymmetric transformation in tris(dithiocarbamato)iron(II) complex. The complex [Fe(S-proOHdtc)3]4- {S-proOHdtc 2- = 1-dithiocarboxyl-4-hydroxy-S-proline(2-)} in methanol shows a large negative CD peak at 600 nm. It suggests that, in the epimerization equilibrium between Δ(S,S,S) and Λ(S,S,S), the Δ(S,S,S) complex is predominant species in methanol. The reaction of NO with Δ(S,S,S)-[Fe(S-proOHdtc)3]4- in methanol shows a decrease of the negative CD peak at 600 nm. This phenomenon of the CD peak decrease shows the NO presence and it can be used for the detection of NO.
