This paper is devoted to the large time behavior and especially to the regularity of the global attractor of the dissipative 1D nonlinear Schrödinger equation with nonlocal integral term on R. We first prove that the existence of the global attractor Aγ in the strong topology of H 1 (R) and the existence of the exponential attractor M which contains the global attractor Aγ, are still finite dimensional, and attract the trajectories exponentially fast. We also show that the global attractor Aγ is regular, i.e., Aγ is included, bounded and compact in H 2 (R) assuming that the forcing term f (x) is of class H 2 (R). Furthermore we estimate the number of the determining modes for this equation. Moreover, we show that the solution trajectories and the global attractor of the nonlocal Schrödinger equation converge to those of the usual Schrödinger equation, as the coefficient of the nonlocal integral term goes to zero.
