  Baryon acoustic oscillations (BAO) are a powerful probe of the expansion
history of the universe, which can tell us about the nature of dark energy. In
order to accurately characterize the dark energy equation of state using BAO,
we must understand the effects of both nonlinearities and redshift space
distortions on the location and shape of the acoustic peak. In a previous paper
we introduced a novel approach to 2nd order perturbation theory in
configuration space using the Zel'dovich approximation, and presented a simple
result for the first nonlinear term of the correlation function. In this paper,
we extend this approach to redshift space. We show how perform the computation,
and present the analytic result for the first nonlinear term in the correlation
function. Finally, we validate our result through comparison to numerical
simulations.
