2007 20160701171657.0 10.1553/cia150s195 DOI ASTROimport-164 Desmet, M. 2007 A spectroscopic study of the ß Cephei star 12 (DD) Lacertae We present first results of a spectroscopic multisite campaign for 12 (DD) Lacertae (hereinafter 12 Lac). This star is one of the best observed ß Cephei stars. It has a large number of known oscillation frequencies but a lack of identified m-values for its detected modes. In our data set we find seven independent frequencies together with combination frequencies. In addition, two of these modes are identified: one radial mode and one prograde dipole mode. Briquet, M.
