Description
We present analysis of high-resolution spectra of a sample of stars in the globular cluster M5 (NGC 5904). The sample includes stars from the red giant branch (RGB; seven stars), the red horizontal branch (two stars), and the asymptotic giant branch (AGB; eight stars), with effective temperatures ranging from 4000K to 6100K. Spectra were obtained with the HIRES spectrometer on the Keck I telescope, with a wavelength coverage from 3700{AA} to 7950{AA} for the HB and AGB sample, and 5300{AA} to 7600{AA} for the majority of the RGB sample.
