| Abstract: | The position and extended fine structure of X-ray K-absorption edge of niobium in its various niobates has been investigated using 400-mm bent crystal (mica, 100 planes) spectrograph. The shift of the K-absorption edge of niobium in its various niobates is related to the size of the next nearest cation; large the size, smaller the shift of the absorption edge towards higher energy side. |
