Infrared attractive fixed points for ratios of O(p^4) couplings are found, which turn out to agree with the values determined from experiment in a surprisingly large number of cases. Infrared attractive fixed line solutions for O(p^6) couplings in terms of O(p^4) couplings and among O(p^6) couplings are determined.9 pages, 2 encapsulated postscript figures, uses epsfig.sty; 2 more postscript figures addedHigh Energy Physics - Phenomenologytext
