Characterization of the crystalline and solution phases in N,N' dimethylethylenediamine (DMEDA) with sodium triflate (NaCF3SO3)
Article Abstract:
The study has led to the discovery of crystalline compound (DMEDA)2 (NaTF)3 characterized by X-ray diffraction, fourier transform infrared spectroscopy, differential scanning calorimetry and Raman spectroscopy. The similarity of vibrational mode frequencies and intensities in the spectral region sensitive to the conformation of DMEDA molecule argues about the comparison modes of DMEDA in the concentrated salt solutions and crystals.

Intra- and intermicellar triplet-triplet annihilation of pyrenetetrasulfonate in an AOT reverse micellar solution: Relation to the electric percolation transition
Article Abstract:
Decay behaviors of triplets are investigated as a function of temperature in ternary and quaternary reverse micellar solutions. The triplet species generated by the laser irradiation of tetrasodium pyrenetetrasulfonate dissolved in a reverse micelle are detected by monitoring the triplet-triplet absorption at 430 nm.
