A high resolution spectrum of a large - sunspot umbra is used for identification of two bands (2-0) and (2-1) of the tex2html_wrap_inline1491- tex2html_wrap_inline1491 system of the FeH molecule, in addition to the previously identified bands (0-0) and (1-0) of the same system. The spectrum was obtained with FTS of the McMath-Pierce Solar Telescope of NSO/NOAO at Kitt Peak.
