  The bound state spectra of the doublet states in three-electron atomic
systems are investigated. By using different variational expansions we
determine various bound state properties in these systems. Such properties
include the electron-nucleus and electron-electron delta-functions and cusp
values. The general structure of the bound state spectra in several
three-electron atomic systems (Li, Be+, C3+ and F6+) is investigated with the
use of the Hylleraas-Configuration Interaction and the Configuration
Interaction wave functions. The advantage of our Configuration Interaction
based procedure is that it provides high numerical accuracy for all
rotationally excited states, including the bound states with L >= 7.
