Abstract:

Beginning with the infrared water ion cluster theory, this report outlines the development of equations leading to the design of an air conductivity cell, which has been fabricated. In earlier work, we showed that anomalous continuum absorption by the atmosphere of infrared radiation could be attributed to intermolecular, hydrogen bonds in polymolecular ion clusters of water which are always present in equilibrium concentrations in samples of water vapor. For example, these clusters can have the form H3O.H2O sub n, where n 10 or 11 in moist air, paired with more mobile ions such as OH-. Therefore, electrical conductivity measurements of moist air should show direct correlations with water cluster concentrations and hence with infrared transmission of the atmosphere. Agreement of preliminary experimental data from the cell with theory is good, suggesting new avenues of investigation in electrostatics such as space charge dissipation. Author
