✦ Synopsis

In this work the fluorescence line narrowing technique has been applied to study the 2E+4A2 emission hand of Cr"+ ions embedded in natural eosphorite (AlPO,(Mn,Fe) (OH)z.2H20) crystals. The 10 K emission spectrum only consists of the inhe mogeneously broadened R, emission band, which appears clearly structured. This structure has been interpreted as a consequence of the presence of four Cr'+ non-equivalent sites.

Samples of monoferric human serum transferrin have been prepared in which the iron occupies predominantly the N-site (sample A) and the C-site (sample B). 111In was then added in concentrations small enough to ensure that there was always an excess of specific binding sites.

For the zeolite offretite, a formula is proposed which includes the framework Si/AI ratio (R), the partitioning ratio of AI over two crystallographically non-equivalent tetrahedral sites (r) and intensities of the observed peaks in the 29Si MAS NMR spectrum. By this formula, the framework Si/AI rati
