Theoretical integrated spectrophotometric quantities, such as spectral line indices in the Lick system (Hbeta, Mg2, Mg b, Fe5270, Fe5335), broadband color indices (in the UBVRIHK and Washington CMT1 bandpasses), and surface brightness fluctuation magnitudes and colors, ranging from far-UV to near-IR have been consistently computed for simple stellar populations from our evolutionary population synthesis code. The age range of -4 Gyr < Deltat < +4 Gyr is explored, where Deltat = 0 Gyr is the currently favored mean age of inner halo Galacitc globular clusters (Galactocentric radius < 8 kpc), ~ 12Gyr. The main aim of this dissertation is to investigate the effects of post-red giant branch stars on the integrated spectrophotometric quantities after employing detailed systematic variation of horizontal-branch morphology with age and metallicity.
