Abstract: We build model spectra of stellar populations at high resolution and with variable α-element enhancements. Analyzing spectra of galactic globular clusters we show that it is possible to derive [Mg/Fe] reliably and efficiently using spectra integrated along the line of sight, thus opening perspectives for investigating the enrichment process in galaxies and star clusters.
