Abstract	Large-cage occupancy of hydrogen (H₂) in the H₂+tetrahydrofuran (THF) hydrates has been ever reported only in the ex situ spectroscopic measurements with the quenched hydrate sample. In the present study, to verify the proof-of-concept for the large-cage occupancy of H₂ competitive with THF, in situ Raman spectra of H₂ in the H₂+THF mixed hydrates were detected at 74.3MPa and 265K without the quenching procedure. The Raman spectra reveal that H₂ molecules occupy a part of large cages of the H₂+THF mixed hydrates at a thermodynamically unstable region of simple H₂ hydrate.
