Abstract:
Spectral properties of 2, 6, 6-trimethyl-3-carbmethoxy-4-phenyl-5-oxo -1,4,5,6,7,8-hexahydroquinoline derivatives (HHQ) with different substituents in the phenyl ring (-Cl, -NO2, -CF3, -CH3, -OCH3) have been studied. Their emission and absorption spectra have been analyzed and quantum yields of emission were determined. The quantum yield of emission was found to depend on the kind, number, and position of substituents in the phenyl ring: it was the highest for the chlorine derivatives of HHQ, and the lowest for the compounds containing -NO2 group.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
