On the Nature of Oxygen Particles in the Low-Temperature Desorption from Vanadium Oxides

The nature of oxygen particles produced in low-temperature desorption from V(2)O(5) and V(2)O(5) center dot MoO(3) was studied. It was found that there was no low-temperature desorption from samples in the presence of a quartz trap cooled to -195 degrees C, which was evidence of the absence of possible desorption of O(3) and the presence of (1)Delta(g) O(2). Under these conditions, the latter was frozen completely, and ozone was not.
