A Fourier Transform Spectrometer has been employed to obtain low and medium resolution spectrophotometry in the range 700 to 10000 cm-1. The method is described briefly and typical data are shown. The technique is applied to a study of 15 K giants, and spectra of 4 and 16 cm-1resolution in the range 4000 to 6500 cm-1 are discussed briefly. CN strong stars are found to be CO strong as well. Five K giants are found to have a relative 13C enhancement over probable primordial abundances.
