Solid-state photochemistry of nitro compounds: structure–reactivity correlations

Solid state and solution nitrate photochemistry: photochemical evolution of the solid state lattice.

We examined the deep UV 229 nm photochemistry of NaNO(3) in solution and in the solid state. In aqueous solution excitation within the deep UV NO(3)¯ strong π → π* transition causes the photochemical reaction NO(3)¯ → NO(2)¯ + O·. We used UV resonance Raman spectroscopy to examine the photon dose dependence of the NO(2)¯ band intensities and measure a photochemical quantum yield of 0.04 at pH 6...

Correlations Between Theoretical and Experimental Determination of Heat of Formation of Certain Aliphatic Nitro Compounds

Heats of formation of energetic materials can be obtained either experimentally or theoretically. In order to compare the results of the two methods, some correlation methods were proposed in this study. The molecular structures and heats of formation of nitrobenzenes, nitrotoluenes, nitroanilines, and nitrophenols were calculated by Dewar's AMI and Stewart's PM3 methods. Correlations of heats ...

SOLID STATE DESEMICARBAZONATION WITH HEXAMETHYLENETETRAMINE-BROMINE: REGENERATION OF CARBONYL COMPOUNDS USING MICROWAVES

Hexamethylenetetramine-bromine on wet alumina rapidly regenerates carbonyl compounds from their corresponding semicarbazone using microwave under solventless system.

Photochemistry of Eichromophoric Compounds : Scope and Expectations

Excitation of molecules containing more than one chromophore leads to intramolecular. interactions such as excimer, exciplexand product -Formation. It is shown in this paper that these interactions can occur even if? the chain connecting them contains several (more than three) units. Different factors affecting these interactions and the relation between the photophysical andphotochemical aspec...
