  We present the results of solar model computation done with the latest
Livermore opacities. Models without diffusion, with hydrogen diffusion only and
with hydrogen and heavy elements diffusion are considered. The influence of
mixing below the convective envelope induced by rotation and angular momentum
losses is also discussed. The sound speed of our best model, does not deviate
from that of Basu's seismic one by more than about one thousandth; p-mode
frequencies are also compared with observations and frequencies for low order p
and g-modes are given.
