We report a detailed in situ study of the preparation of the -phase Bi 2 MoO 6 catalyst from a gel. In particular, the local coordination around molybdenum remained tetrahedral, although the poorly crystalline bismuth molybdate phase started to appear below 4003C; above this temperature there was a
## Abstract A new band at 896 cm^−1^ is ascribed to a local mode, __v__~1~, due to a molybdate ion occupying a cation vacancy. Local modes for __v__~3~ and __v__~4~ were also found at __ca.__ 800 and 397 cm^−1^, respectively. The relative intensity for translational modes at 71 and 59 cm^−1^ varied
