Abstract
Asteroseismology relies on accurate mode identification.High-resolution spectroscopy allows to detect such crucial informationas the pulsational degree ℓ, the azimuthal number m, andpulsation amplitudes, directly from time series of observations. Theadvantage of high-resolution spectroscopy over standard photometrictechniques is that not only pulsational temperature variations can bedetected, but also the pulsational velocity field, yielding valuableextra information.In this paper I review the mode-identification methods that havebeen developed over the last decades, with emphasis on theapplication to hot main-sequence stars.
