The XANES or NEXAFS regions associated with the K-edges of zinc and ni
ckel in polymer electrolytes based on PEO(n):MBr(2) systems have been
examined. The results for the very dilute zinc systems (where n = 1000
, 2000, 3000, 4000; 5000) and the plasticised and unplasticised nickel
systems are compared with previously reported data from the EXAFS reg
ions of the spectra.
