Influence of residual phases on the behaviour of gradual spin transition complexes

In order to interpret the large shift between the observed high spin fracti on and the so-called molar high spin fraction in the Mossbauer study on gra dual spin transition complexes, we reveal numerically that the effects from residual phases in the substance should be considered in the correction by Debye-Waller factors. This result shows that similar Debye-Waller factors in high and low spin states agree well with the conclusion of experimental investigations for such gradual spin transition complexes.
