Simulation of Ozone Gas Absorption Cross-Section: A Concentration-Based Analysis for Green Communication

Abstract

This chapter explores the impact of ozone concentration on its absorption cross section in the visible spectrum. We used a computer program called Spectralcalc. com and a database of ozone absorption lines (HITRAN 2012 line list) to simulate how ozone absorption cross-section changes with different concentrations. While transmittance through a 50 cm gas cell exhibited a continuous dependence on concentration, the absorption cross section of 5.1055×10-25m2 /molecule itself remained constant for wavelengths around 603 nm at concentrations of 170 ppm and above. This finding deviates slightly (between 1.41 and 2.44%) from previous studies. Our simulations suggest that ozone concentrations between 170 and 1200 ppm have a negligible effect on the absorption cross section at this specific wavelength.
