We present results of an asteroseismic study on the γ Dor type Kepler target KIC 6462033. Kepler photometry is used to derive the frequency content and principal modes. High-dispersion ground-based spectroscopy is also carried out in order to determine the atmospheric parameters and projected rotational velocity. From an analysis of the Kepler long cadence time series, we find that the light curve of KIC 6462033 is dominated by three modes with frequencies f1 = 0.92527, f2 = 2.03656 and f3 = 1.42972 d-1 as well as we detect more than a few hundreds of combination terms. However, two other independent frequencies appear to have lower amplitudes in addition to these three dominant terms. No significant peaks are detected in the region >5 d-1. We therefore confirm that KIC 6462033 pulsates in the frequency range of γ Dor type variables, and a future study will allow us to investigate modal behaviour in this star.
