The broadening and shifting of spectral lines induced by collisions with the five noble gases in both the intercombination 5s{sup 2} {sup 1}S{sub 0}{yields}5s5p {sup 3}P{sub 1} system and the triplet 5s5p {sup 3}P{sub 0,1,2}{yields}5s6s {sup 3}S{sub 1} manifold of Sr are studied using tunable dye laser absorption spectroscopy. Cross sections for impact broadening and line shifting are determined from an examination of the spectral line profiles. These results are utilized in an analysis to compute difference potentials modeled by the Lennard-Jones (6-12) potential and the coefficients C{sub 6} and C{sub 12} derived from this analysis are reported.
