Study of the effect of perturber mass on collisional broadening coefficients of lines in the ν3 band of CS2

► He-broadening of lines in the ν3 band of CS2 were measured accuracy. ► Ne-broadening of lines in the ν3 band of CS2 were measured accuracy. ► Kr-broadening of lines in the ν3 band of CS2 were measured accuracy. ► The line parameters were measured by high resolution diode-laser spectroscopy. ► The line parameters were deduced from Voigt, Rautian-Sobel'man and Galatry fits.
