Scientific paper

Intermediate resolution spectra in the wavelength region 1.6 to 2.4 microns have been obtained of four luminous M31 clusters. The mean M31 cluster spectrum is compared with spectra of Galactic globular clusters and elliptical galaxies. It is concluded that the CO bands in the mean M31 cluster spectrum have strengths consistent with the metallicities of the clusters. However, the CN bands at 2 microns appear to be enhanced. Burstein et al. (1984) have found CN to be abnormally strong in the blue spectra of luminous M31 clusters, and it is suggested that some sort of primordial enrichment may be required to explain the presence of CN enhancement over a broad range of wavelengths.
