| Abstract: | The orbital elements of HD 54901, HD 120544 and HD 123280, three nearby F‐type spectroscopic binaries, are presented. They are based on observations made between 1982 and 2004 with the CORAVEL instrument of Observatoire de Haute‐Provence. Physical parameters are derived for the two components of HD 54901 (SB2) and for the primaries of HD 120544 and HD 123280. The rotation‐revolution synchronism of the detected components is investigated. Pseudosynchronism is very likely achieved by the F7 V secondary component of HD 54901, whereas the F2/3 IV primary has not yet reached this stage. (© 2004 WILEY‐VCH Verlag GmbH & Co.
