Abstract

The superficially normal stars {theta} And (A2 V), {epsilon} Del (B6 III), {epsilon} Aqr (A1.5 V), and {iota} And (B9 V), which have rotationally broadened line profiles, are analyzed in a manner consistent with previous studies of this series using 2.4{AA}/mm spectrograms obtained with CCD detectors and S=N>=200. Their variable radial velocities strongly suggest they are spectroscopic binaries. As no evidence is seen for lines of their companions they are analyzed as single stars. Their derived abundances are generally near solar. But those for {theta} And suggest that it is possibly a fast rotating Am star.
