The general features of the expressions useful for numerical calculations of the projected deformed Hartree-Fock (HF) spectra for finite nuclei are investigated. It is proved that the projected deformed HF wave-function gives the possible nuclear spins as I=0,2,4,...,I<SUB>max</SUB> for a K=0 band and I=K,K+1,...,I<SUB>max</SUB> for a K≠0 band. It is further proved that if the energy E<SUB>I=K</SUB> of the projected I=K state is greater (less) than the HF energy E<SUB>K</SUB><SUP>HF</SUP>, then E<SUB>I</SUB> is greater (less) than E<SUB>I</SUB>' for I<I'. A plausible reason why one should use the deformed HF state rather than any other deformed state is also pointed out
