摘要: A complete spectrum criterion and a next nearest neighbor model are proposed. Research indicates: 1) Using this criterion can remove the long existing puzzle that different parameters produce different bond lengths. The criterion greatly improve the reliability of optical method for determining the Mn2+-F- distance R. 2) The exponent n and coefficient K in the inverse power law 10Dq=KR-n are obviously affected by next nearest neighbor. 3) Considering the effect can lead to a better result, the next nearest neighbor model is thus more strict and reliable.
