We present new white dwarf chemical profiles appropriate for pulsational studies of ZZ Ceti stars on the basis of full evolutionary calculations for both white dwarfs and progenitor stars. We perform adiabatic pulsation calculations, and find that the whole g-mode period spectrum and the mode-trapping properties of ZZ Ceti stars as derived from our new chemical profiles are substantially different from those based on chemical profiles widely used in existing asteroseismological studies. Thus, we expect the asteroseismological models derived from our chemical profiles to be significantly different from those found thus far.
