Analysis of combined isotropic and anisotropic line-width data with a view to improved rotational CARS thermometry

Includes bibliographical references.The development of a new line-width model and recently measured rotational (anisotropic) line-widths has allowed for a critical analysis of the various basis rates models. These basis rates will be analysed using both vibrational (isotropic) and rotational line-width data. The data sets are analysed individually and in combination. For all fits, parameter correlations are determined. In addition, the sensitivity of the goodness of fit to variations in the effective interaction length for collisions, le, is investigated. To complete the investigation full rotational spectra are calculated and compared with experimental spectra
