THE BAND-FITTING ANALYSIS OF THE RAMAN-SPECTRA CLOSE TO PHASE-TRANSITIONS

1988-05-01
Curve-fitting techniques are quite widely used in science to improve the significance of data derived from experimental measurements. Here we wish to draw attention to the advantages that can be gained by applying such techniques in spectroscopy in apparently more straight-forward situations. Our interests were in the problem of measuring and interpreting small but highly significant changes in frequency, bandwidth or intensity in the vicinity of phase transitions. A computer programme of the non-linear least squares type was developed and used to analyse our Raman data for ammonium halides close to phase transitions. Our form of analysis will be described in detail
