A method of analysis of polarographic waves of simple electrode processes is proposed. The quasi-reversible half-wave potential, Ec1/2, is involved in the determination of thermodynamic and kinetic parameters of electrode processes. This potential is determined very easily and with great precision. In order to facilitate the use of the method proposed, we have developed a computer program for Windows.

Thermodynamic And Kinetic Parameters

The dependence of partial photochemical quantum yields on temperature and light intensity was examined with two dihydroindolizines. Some nonlinear optimization procedures and least squares methods are used to solve the system of differential equations. The distinct influence of the competitive thermal reaction can be demonstrated for both photochromic systems by determination of thermodynamic and kinetic parameters.
