✦ Synopsis

Matsen equations are used in order to calculate, for the investigated compounds, related series of ionization potentials and electron affinities in gaseous phase, aqueous solution and in the photographic emulsion.

More especially, peak and conventional polarographies are used to determine the oxidation and reduction potential terms as well as the work function of graphite. The salvation energy terms are evaluated on the basis of a Born equation.

It appears that reliable values of electron affinities in the emulsion for cyanine dyes are better determined from corresponding values of their ionization energies and values of transition energies obtained from sensitization spectra.

The ionization potential (IP), electron affinity (EA) and energy gap (E,) of polyimide are estimated from molecular orbital (MO) computations using the AMI method on model compounds. Their computed values are 8.5, 1.4 and 7.1 eV, respectively. Interestingly, it was found that the EA of polyimide is
