The decomposition process of orthorhombic hydrogen molybdenum bronze, H<SUB>0.30</SUB>MoO<SUB>3</SUB>, was studied by the temperature programmed decomposition (TPD) technique <I>in vacuo</I> and in helium gas. The only gas liberated during the decomposition was H<SUB>2</SUB>O and no other gas was detected. The TPD spectrum above 150 °C was composed of three bands (PII, PIII, and PIV). The PII band corresponded to the process from H<SUB>0.30</SUB>MoO<SUB>3</SUB> to H<SUB>0.21</SUB>MoO<SUB>2.95</SUB> without any structural change. The PIII band corresponded to the process from H<SUB>0.21</SUB>MoO<SUB>2.95</SUB> to H<SUB>0.06</SUB>MoO<SUB>2.88</SUB> with the structural change and the PIV band, to the process from H<SUB>0.06</SUB>MoO<SUB>2.88</SUB> to MoO<SUB>2.85</SUB>.
