Changes with time in mass and absorbance, accompanied by the dioxygenation of Mo<SUP>IV</SUP>O(tmp) (tmp = 5,10,15,20-tetramesitylporphyrinato dianion) at room temperature in the sublimated solid film, were simultaneously followed by an <I>in situ</I> quartz crystal microbalance (QCM)/UV-vis spectroscopy combined method. The two curves synchronized accurately. In the most cases of the film systems with (2.34 - 7.13) × 10<SUP>−8</SUP> mol cm<SUP>−2</SUP> of coverage, the dioxygenation attained ca. 82% completion in 120 s in dry dioxygen atmosphere.
