Spectroelectrochemistry File Format

General format

The data for all spectra are written in a separate file. For spectroelectrochemical experiments, the file names consist of the prefix SpectraFor_ followed by the file name of the spectro-electrochemical experiment.

With the script OpticalSpectroscopy.exp, a single spectrum is recorded without any electrochemical experiments. The file name for this experiment does not automatically contain the prefix SpectraFor_.

The tag for all spectroscopy files is called SPECTROSCOPY, which is written in the second line of the data file.

The next line contains the data type that is recorded and saved in the file. The type of this line is called IQUANT. It follows an INDEX number which defines the data type that is recorded for a spectrum (see table).

After this, the data for each single spectrum follow each other without any interruption.

The data for a single spectrum consist of the type IQUANT which follows a value defining the current measurement time in seconds. The tag of this line is TIME.

The next line includes the TABLE type. The special tag for spectroscopic measurements is SPECTRUM. Furthermore, both tags TIME and SPECTRUM include a consecutive number starting at zero (0) showing the current number of the spectrum.

The actual spectral data are listed in two columns: the wavelength in nanometers (nm) and the data type that you selected in the setup. This can be Absorbance, Raw Counts, or Transmittance.

Raman format

The file format is basically the same as for all other spectroscopic experiments. There are only two differences:

  1. There is only a single INDEX instead of three. INDEX 10 represents Raw Counts as data type
  2. The wavenumber (1/cm) is saved instead of the wavelength (nm). The second column lists only raw counts as data type and not absorbance or transmittance.
