The interpretation of Mossbauer spectra often requires the use of the Transmission Integral function (TI).

Abstract
The interpretation of Mossbauer spectra often requires the use of the Transmission Integral function (TI). It contains the quantity fs/(1+B),where fs is the source Mossbauer factor and B depends on the background radiation rate and on the inhomogeneity of the target: both of them usually obtained by ancillary measurements and tests. We present a simple method, that avoids ancillary measurements in evaluating the quantity fs/(1+B). It is useful when the Mossbauer line-shape rapidly evolves in narrow temperature ranges: a real application for single molecule magnets spectra and an analytical example are reported, too
