摘要：

Micro-crystals of the polymer were found to absorb an amount of gas equivalent to approximately two molecules per unit cell. Analysis of x-ray structural data suggested that the absorbed O//2 must reside on the surface or at crystalline defects. Adsorption of **1**6O//2 and **1**8O//2 on the surface of macro-crystals was monitored by the appearance of extra lines in the resonance Raman spectrum. Excitation profiles of the extra lines indicate that the presence of O//2 induced additional electronic transitions at 2. 4 and 2. 6 ev.
