Query: Towards Asteroseismology of PG1605+072   We present our attempt to characterise the frequency spectrum of the bright V
361 Hya star PG1605$+$072 from atmospheric parameter and radial velocity
variations through a spectroscopic approach. Therefore we used time resolved
spectroscopy ($\approx$9000 spectra) to detect line profile variations from
which variations of the effective temperature and gravity, together with their
phases, are extracted by means of a quantitative spectral analysis. The
theoretical modelling of adequate pulsation modes with the \textit{BRUCE} and
\textit{KYLE} codes allows to derive constraints on the mode's degree and order
from the observed frequencies.
