High-resolution near-infrared spectra of NGC 6624 and 6569

We present the first abundance analysis based on high-resolution infrared (IR) echelle spectra of NGC 6569 and 6624, two moderately reddened globular clusters located in the outer bulge of the Galaxy. We find [Fe/H] = -0.79 +/- 0.02 and -0.69 +/- 0.02 dex for NGC 6569 and 6624, respectively, and an average alpha-element enhancement of approximate to +0.43 +/- 0.02 and +0.39 +/- 0.02 dex, consistent with previous measurements on other metal-rich bulge clusters. We measure accurate radial velocities of < v(r)> = -47 +/- 4 and +51 +/- 3 km s(-1) and velocity dispersions of approximate to 8 and 6 km s(-1) for NGC 6569 and 6624, respectively. Finally, we find very low C-12/C-13 isotopic ratio (<= 7 in NGC 6624 and approximate to 5 in NGC 6569), confirming the presence of extramixing mechanisms during the red giant branch evolution phase.
