Abstract
We used extensive ground-based multisite and archival spectroscopy to derive observational constraints for a seismic modelling of the magnetic Cep star V2052 Ophiuchi. The lineprofile variability is dominated by a radial mode (f 1 = 7.148 46 d -1 ) and by rotational modulation (P rot = 3.638 833 d). Two non-radial low-amplitude modes (f 2 = 7.756 03 d -1 and f 3 = 6.823 08 d -1 ) are also detected. The four periodicities that we found are the same as the ones discovered from a companion multisite photometric campaign and known in the literature. Using the photometric constraints on the degrees of the pulsation modes, we show that both
