  We analyze a time series of optical spectra of SN~2014J from almost two weeks
prior to maximum to nearly four months after maximum. We perform our analysis
using the SYNOW code, which is well suited to track the distribution of the
ions with velocity in the ejecta. We show that almost all of the spectral
features during the entire epoch can be identified with permitted transitions
of the common ions found in normal SNe Ia in agreement with previous studies.
  We show that 2014J is a relatively normal SN Ia. At early times the spectral
features are dominated by Si II, S II, Mg II, and Ca II. These ions persist to
maximum light with the appearance of Na I and Mg I. At later times iron-group
elements also appear, as expected in the stratified abundance model of the
formation of normal type Ia SNe.
  We do not find significant spectroscopic evidence for oxygen, until 100 days
after maximum light. The +100 day identification of oxygen is tentative, and
would imply significant mixing of unburned or only slight processed elements
down to a velocity of 6,000 km/s. Our results are in relatively good agreement
with other analyses in the IR. We briefly compare SN 2011fe to SN 2014J and
conclude that the differences could be due to different central densities at
ignition or differences in the C/O ratio of the progenitors.
