Dielectric: General Description¶

Purpose ¶

Application to Analyze Dielectric Spectroscopy Data

Data Files ¶

The first line of the file should contain the sample parameters separated by semi-colons (;). It may contain any number of parameters which will be read and saved as file-parameter in RepTate.
Then the data columns should appear, separated by spaces or tabs.

`.tts` extension ¶

Warning

NEEDS TO BE DONE

Text files with .dls extension should be organised as follows:

.dls files should contaion at least the parameter values for the:
1. sample molar mass Mw,
2. temperature T.
3 columns separated by spaces or tabs containing respectively:
1. frequency, \(\omega\),
2. elastic modulus, \(G'\),
3. loss modulus \(G''\).

Other columns will be ignored. A correct .tts file looks like:

T=-35;CTg=14.65;dx12=0;isof=true;Mw=13.5;chem=PI;PDI=1.04;
