Fourier Transform Infrared Spectroscopy (FTIR) dataset
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following
`FTIR dataset `_,
was obtained as a JCAMP-DX file, and subsequently converted to the CSD model
file-format. The data structure of the FTIR dataset follows,
.. code-block:: default
import csdmpy as cp
filename = "https://osu.box.com/shared/static/0iw0egupb1hkulkbdq4hagzzhkbvqjkv.csdf"
FTIR_data = cp.load(filename)
print(FTIR_data.data_structure)

Because, FTIR spectrum is conventionally displayed on a reverse axis, an
optional `reverse_axis` argument is provided to the :meth:`~csdmpy.plot` method.
Its value is an order list of boolean, corresponding to the order of the
dimensions.
