Abstract
In the present work, the MSF computer code is presented intended for determination of the spectral line parameters by their simultaneous fitting to the several absorption spectra recorded under different conditions. Line positions, intensities, pressure broadening and shift coefficients, and lower state energies of dipole transitions in a molecule can be determinable parameters. Basic concept, algorithm, and capabilities of the MSF computer code are outlined in the paper.
