• SFG Fitter v 6.6

  • This program is specifically designed to fit data resulting from infrared-visible sum frequency generation spectroscopic measurements.  The program is capable of fitting multiple spectra simultaneously, can correctly account for signal generated from non-resonant sources, and can perform automated fitting tasks.  The zip file contains the executable file, example data files, an explanation of error messages, and an overview of the fundamentals of operation.  More documentation can be made available upon request.

• Constant Heating Rate Relaxation

  • This program fits relaxation data in experiments where polymeric samples are heated at constant rates.  The relaxation phenomena are assumed to follow a WLF type relaxation below T_g and a Kohlrausch-Williams-Watts type relaxation above T_g.  The user interacts with the program through the file "parameterfile.dat".  The zip file contains the executable file, an example data file, and an overview of the fundamentals of operation.  More documentation can be made available upon request.
