AUTOMATION OF DIPOLE-MOMENT MEASUREMENTS USING MICROPROCESSOR-CONTROLLED SYSTEM

A microprocessor controlled instrument that; can be used in physical c hemistry research laboratories has been designed and constructed. The intended use is the measurement,of the dipole moment and determination of the temperature dependency of the dipole moment far polar substanc es; especially for macromolecules, Measurement techniques with convent ional dipolmeters require fine adjustments and measurements which seem to bt very tedious and time consuming. Provided automation enables ve ry frequent measurements with a step of 1 degrees C and disallows any user-oriented error. The dielectric constant measurement is performed within an accuracy limit of less than +/- 0.001. Furthermore, the equi pment designed provides the opportunity of processing and evaluating t he data obtained with the use of a personal computer.
