Recently, there has been growing experimental evidence for redshifts in line spectra from highly ionized, high-Z radiators immersed in hot, dense plasmas [O. Renner , J. Quant. Spectrosc. Radiat. Transf. 58, 851 (1997); C. F. Hooper , in Strongly Coupled Coulomb Systems (Plenum, New York, 1998); N. C. Woolsey , J. Quant. Spectrosc. Radiat. Transf. 65, 573 (2000); A. Saemann , Phys. Rev. Lett. 82, 4843 (1999)]. A full Coulomb, multielectron formalism of line broadening due to perturbation by plasma electrons will be presented. A red line shift and asymmetries arise naturally from employing a full Coulomb expression for the perturber-radiator interaction, rather than applying the dipole approximation. This formalism can now be applied to arbitrary multielectron radiating ions.
