The emission spectra of the A² - X^{2 +} and B^{2 +} - X^{2 +} systems of ScS have been observed in the 10000-13500 cm^-1 region using a Fourier transform spectrometer. A rotational analysis of the 0-1, 0-0 and 1-0 bands of the A² _3/2 - X^{2 +} and 0-1, 0-0, 1-0, 2-0 and 3-1 bands of the B^{2 +} - X^{2 +} systems has been obtained and improved spectroscopic constants have been extracted for the electronic states of ScS.
