The present work reports measurements of the spectral absorptivities of the eight significant infrared bands for methyl methacrylate vapor. The experimental data were taken at low resolution for temperatures between 400 and 680#xA0;K and at a total pressure of 1 atm. Analysis of these data by the statistical narrow-band model yields the spectral-mean parameters for each band, while the wideband parameters have been correlated using both the exponential wide-band model and the Tien-Lowder continuous correlation. These correlated parameters allow convenient determination of the total emissivity, the Planck mean absorption coefficient and super-band parameters.
