The Gross Llewellyn Smith sum rule has been measured at different values of four-momentum transfer squared (Q{sup 2}) by combining the precise CCFR neutrino data with data from other deep-inelastic scattering experiments at lower values of Q{sup 2}. A comparison with the {Omicron} ({alpha}{sub s}{sup 3}) predictions of perturbative QCD yields a determination of {alpha}{sub s} and its dependence on Q{sup 2} in the range 1GeV{sup 2} < Q{sup 2} < 20 GeV{sup 2}. Low Q{sup 2} tests have greater sensitivity to {alpha}{sub s} (M{sub Z}{sup 2}) than high Q{sup 2} tests, since at low Q{sup 2} {alpha}{sub s} is large and changing rapidly.
