Recent studies have highlighted the potential of jet substructure techniques to identify the hadronic decays of boosted heavy particles. These studies all rely upon the assumption that the internal substructure of jets generated by QCD radiation is well understood. In this article, this assumption is tested on an inclusive sample of jets recorded with the ATLAS detector in 2010, which corresponds to 35 pb -1 of pp collisions delivered by the LHC at Rs = 7TeV. In a subsample of events with single pp collisions, measurements
corrected for detector efficiency and resolution are presented with full systematic
uncertainties. Jet invariant mass, kt splitting scales and N-subjettiness variables are presented for anti-kt R = 1.0 jets and Cambridge-Aachen R = 1.2 jets. Jet invariant-mass
spectra for Cambridge-Aachen R = 1.2 jets after a splitting and filtering procedure are
also presented. Leading-order parton-shower Monte Carlo predictions for these variables
are found to be broadly in agreement with data. The dependence of mean jet mass on
additional pp interactions is also explored
