This talk will present studies of the spin, parity and tensor couplings of the Higgs boson in the H → ZZ* → 4l, H → WW* → eνµν and H → γγ decay processes at the LHC, based on 25 fb-1 of pp collision data collected by the ATLAS experiment at 7 TeV and 8 TeV. The Standard Model (SM) Higgs boson hypothesis, corresponding to the quantum numbers JP = 0+, is tested against several alternative spin scenarios, including non-SM spin-0 and the spin-2 models with universal and non-universal couplings to fermions and vector bosons. Using the H → ZZ* → 4l and H → WW* → eνµν decays, the tensor structure of the HVV interaction in the spin-0 hypothesis is also investigated.
