  We have determined spectroscopic orbits for five single-lined spectroscopic
binaries, HD 100167, HD 135991, HD 140667, HD 158222, HD 217924. Their periods
range from 60.6 to 2403 days and the eccentricities, from 0.20 to 0.84. Our
spectral classes for the stars confirm that they are of solar type, F9 to G5,
and all are dwarfs. Their [Fe/H] abundances, determined spectroscopically, are
close to the solar value and on average are 0.12 greater than abundances from a
photometric calibration. Four of the five stars are rotating faster than their
predicted pseudosynchronous rotational velocities.
