  The solar chromosphere has historically been studied from spectral lines in
the visible and UV, notably H{\alpha}, Ca ii, Mg ii and Ly{\alpha}.
Observations at long UV wavelengths (304, 1600 and 1700 {\AA}) from space have
been recently added. However, the chromosphere can also be studied in the
infrared (IR), both in the continuum as in the lines. Studies in this spectral
band, which by definition extends from 1 {\mu}m to 1 mm, are scarce and recent,
and its advantages having been little explored. In this work we present a
review of what has been done and detail how much can be done with ground-based
instruments. Argentina has a set of unique telescopes for the observation of
the chromosphere, some with more than 20 years of operation and in process of
renovation, others recently installed and still some in development. The
panorama is very encouraging and allows to anticipate a strong international
cooperation with other ground and space facilities.
