Linear Correlations

Redox potentials determined by cyclic voltammetry were used in conjunction with published electron affinities to determine the solvation energies for series of three classes of compounds: substituted benzoquinones, substituted nitrobenzenes, and polynuclear aromatic hydrocarbons. Excellent linear correlations were obtained between the measured electron affinities and the E0 of the substrates. The calculated electron affinities, EA (E0), were computed using the average solvation energies for the three classes of compounds, and were found to be in excellent agreement with the measured values. The nitrobenzenes and quinones had one solvation energy, while the aromatic hydrocarbons were correlated with a significantly different value. The solvation energy of a variety of compounds could also be related to their Marcus reorganization energiesλ(0), by a linear plot with a high correlation coefficient. From simple electrochemical measurements of similar compounds, either electron affinities or Marcus λ(0) values can be estimated. Keywords: electron affinities, Marcus reorganization energies, cyclic voltammetry.

Bay quinones have the carbonyl oxygen atoms in the bay region of polycyclic aromatic hydrocarbons. This study presents cyclic voltammetry and computational work helping to understand when bay quinones can be expected to be isolable, and when not.

Sunspot Groups

AbstractData on sunspot groups have been quite useful for obtaining clues to several processes on global and local scales within the sun which lead to emergence of toroidal magnetic flux above the sun’s surface. I present here a report on such studies carried out at Indian Institute of Astrophysics during the last decade or so.
