Abstract
- Abstract: Transitions of pure carbon dioxide have been measured using a Fourier transform spectrometer in the 30012←00001 and 30013←00001 vibrational bands. The room temperature spectra, recorded at a resolution of 0.008cm−1, were analyzed using the Voigt model and a Speed Dependent Voigt line shape model that includes a pressure dependent narrowing parameter. Intensities, self-induced pressure broadening, shifts, and weak line mixing coefficients are determined. The results obtained are consistent with other studies in addition to the theoretically calculated values. Exponential Power Gap (EPG) and Energy Corrected Sudden (ECS) scaling laws were used to calculate the relaxation matrix elements. [Copyright &y& Elsevier]
