resolution between 4100 and 5500 A ˚ . A full description of the assignments and spectral features in the stars is given. The spectra are characterized by absorption from the ground vibrational level (0, 0, 0) and from higher-lying vibrational levels involving one quantum of excitation in n 1, and up to two quanta in n 2 and n 3, giving rise to numerous hot-bands. The first results of rotational contour calculations are presented, and are consistent with SiC2 lying in the upper atmosphere of the star with a rotational temperature substantially lower than that of the photosphere.
