High-resolution spectra of sulfur dioxide have been recorded between 1055 and 2550 cm-1 using infrared Fourier transform spectroscopy. More than 18 000 recorded lines have been assigned to nine cold and four hot vibration-rotation bands of SO2. Precise values of the band centers, rotational and centrifugal parameters, and anharmonic constants have been determined that allow one to reproduce and to predict the energy spectrum of SO2 and its isotopic species with high accuracy.
