The emission spectra of the $A2\Pi -X2\Sigma +$ and $B2\Sigma +-X2\Sigma +$ systems of ScS have been observed in the $10000-13500$ cm$\mathrm{<mrow\; data-mjx-texclass="ORD">-1</mrow>}$ region using a Fourier transform spectrometer. A rotational analysis of the $0-1$, $0-0$ and $1-0$ bands of the $A2\Pi 3/2-X2\Sigma +$ and $0-1$, $0-0$, $1-0$, $2-0$ and $3-1$ bands of the $B2\Sigma +-X2\Sigma +$ systems has been obtained and improved spectroscopic constants have been extracted for the electronic states of ScS.
