Tutorial01

Fitting the complex refractive index by automatic mode

---

In this tutorial, we will use the C=O stretching region of dimethyl carbonate (DMC) as an example to show the automatic fitting procedure in ComplexRI.

The ATR-IR experimental data file in this tutorial can be downloaded on the manual page of ComplexRI package.

Here, Click “download the File 01” to download the file. The filename name should be “data_DMC_2col.txt”.

Then, please move to the Perform Fitting page.

Upload the“data_DMC_2col.txt”in ① and set the other parameters according to the following figure. (For the meanings of each part, please refer to Manual➡ComplexRI#Manual.)

Now, please click the “Execute LSR” to start fitting.

Explanation of Tutorial01

Result should be like below.

[図1-1]

Please, Click "download the output file" to download the outputfile, and check if the name is the same as the value you give in the input field①.

This is the basic flow of ComplexRI. In the next tutorial, you can practice to input the values to other input fields.

Here, we explain only the format of input file.

The content of file you downloaded should be like above. There are the wavenumber and the corresponding reflectance in the first columns and second columns respectively.

We explain the result in Output.
