We investigate the Q^2-dependence of both the flavor non-singlet and the singlet Nachtmann moments of deep inelastic structure functions in the framework of QCD with full order-g^<-2> corrections. The non-singlet moments-data are consistent with QCD as have been claimed so far. The order-g^<-2> corrections are absorbed almost to the resetted value of scale parameter. However, there is a certain inconsistency among several approximation-schemes as will be discussed in detail. For the singlet moments the order-g^<-2> corrections are shown to be very important to remove the discrepancy claimed recently by Duke and Roberts. We conclude that the QCD prediction for singlet moments is also not inconsistent with present experiments.
