Integrated spectra of Milky Way globular clusters ( GCs ) are reproduced by computing synthetic spectra taking into account individual element abundances .
Five clusters were selected from their location in the Galactic bulge , for which integrated spectra were available in the WiFeS Atlas of Galactic Globular Cluster Spectra project .
Our aim is to further study the oldest GC located in the Galactic bulge , with a metallicity in the range - 1.6 < [ Fe/H ] < - 0.7 .
We also include the halo cluster NGC 6752 for comparison purposes .
We reproduce the full spectra in the range 4500-9000 Å available in these observed spectra , as well as individual lines of Na , Mg , Al , Si , Ca , Ti , Ba , and Eu .
We report a list of lines that are suitable for abundance derivation , and by adopting these abundances we are able to fit the damping parameters that define the wings of strong lines of well-known triplets of Mg I and Ca II .
Finally , the effect of multiple stellar populations through enhanced Na abundances is tested .
