Hi All,
I was looking at emission spectra of some organic compounds and I have observed that when they are in water or in any other media then air they show red shift in their emission spectra? Can anyone share some literature with me why is that?
For the case that the compound is not altered in the solvent, there is Kundt's rule for absorption, which states that the absorption is redshifted the more the stronger optical dispersion (change of the index of refraction) of the solvent is. The original paper is from 1878: Kundt, A., Ueber den Einfluss des Lösungsmittels auf die Absorptionsspectra gelöster absorbierender Medien. Annalen der Physik 1878, 240 (5), 34-54.
I proved Kundt's finding (about half of the solutions follow Kundt's rule) more or less by accident recently by electromagnetic theory, but I cannot give you a reference for this yet.
I am working on the optical properties of organic compounds. This is due to long pi conjugation system in the molecular structure and aggregation formation in the organic semiconductor material. Your material is colored is well.
