We present radial velocities and chemical abundances for red giant branch stars in the Galactic bulge globular clusters NGC 6342 and NGC 6366 .
The velocities and abundances are based on measurements of high resolution ( R \gtrsim 20,000 ) spectra obtained with the MMT–Hectochelle and WIYN–Hydra spectrographs .
We find that NGC 6342 has a heliocentric radial velocity of + 112.5 km s ^ { -1 } ( \sigma = 8.6 km s ^ { -1 } ) , NGC 6366 has a heliocentric radial velocity of –122.3 km s ^ { -1 } ( \sigma = 1.5 km s ^ { -1 } ) , and that both clusters have nearly identical metallicities ( [ Fe/H ] \approx –0.55 ) .
NGC 6366 shows evidence of a moderately extended O–Na anti–correlation , but more data are needed for NGC 6342 to determine if this cluster also exhibits the typical O–Na relation likely found in all other Galactic globular clusters .
The two clusters are distinguished from similar metallicity field stars as having larger [ Na/Fe ] spreads and enhanced [ La/Fe ] ratios , but we find that NGC 6342 and NGC 6366 display \alpha and Fe–peak element abundance patterns that are typical of other metal–rich ( [ Fe/H ] > –1 ) inner Galaxy clusters .
However , the median [ La/Fe ] abundance may vary from cluster–to–cluster .
