- In a manner similar to the UV-absorption, the excimer fluorescence emission of la [meso] in aqueous solution was affected by the presence of less-polar aprotic solvent THF or dioxane.
- For Bchl and Chl dissolved in diethyl ether, toluene, acetone, ethanol and acetonitrile, the Mg atom was found to be pentacoordinated, whereas it was hexacoordinated in dioxane, tetrahydrofuran, pyridine and methanol.
- Carcinogens, such as dioxane and nitrosamine, are commonly formed in synthetic concoctions and are virtually impossible for us to know about.
