摘要：

The applicability of positron annihilation spectroscopy for chemical structural problems is demonstrated by two examples: For the swelling dynamics of an amphiphilic polymer network, very quick structural changes were indicated by positronium lifetime parameters at very low swelling ratios and a hydration mechanism was proposed accordingly. For the series [Fe(x)Zn(1-x) (propyltetrazole)(6)](BF(4))(2)(x = 1, 0.6, 0.4, 0.1, 0), changes in the dynamic structure were revealed by positronium lifetime spectroscopy. For compounds of x > 0, temperature-induced spin-crossover was detected. (C) 1999 Elsevier Science Ltd. All rights reserved.
