We present time-resolved spectroscopy of two pulsating stars using VLT UT1. Primary aim is an identification of the pulsation modes from the wavelength dependency of the amplitudes. A mode identification is the prerequisite to make full use of the photometric data obtained for asteroseismologic studies.
