Abstract
A brief review of the classic distinctions between glasses, liquids, and crystals is given. Using ferrous chloride in H2O as a model system, how these distinctions appear in Mössbauer spectroscopy is shown. The shape of the narrow absorption lines produced in these glasses is discussed, and argument is made for nearly perfect shortrange order. The second system discussed is ferrous ion dilute in H3PO4·H2O. This solution is most difficult to crystallize, allowing long measurements well above the glass-transition temperature Tg. The main effects with increasing temperature in this system are decreasing amplitudes and broadening line widths. In addition we see here clear changes in the slope vs. temperature at Tg of such parameters as line width, quadrupole splitting, and area. The quadrupole splitting decreases more rapidly with temperature above Tg than suggested by extrapolation from lower temperatures; a relaxation of the direction of the EFG, as calculated by Blume, seems to be the explanation.

Misfit, a suggested goodness-of-fit parameter, is a normalized modification of 2 such that (1) its value is independent of the duration of the run, (2) “normal” instrumental inadequacies lead to Misfit values of< 0.1% for 57Fe experiments, (3) the error in Misfit clarifies whether a small 2 results from (a) good theory or (b) poor data.
