Abstract
Based on the 4D momentum, the influence of quintessence on the gravitational frequency shift and the deflection of light are examined in modified Schwarzschild space. We find that the frequency of photon depends on the state parameter of quintessence : the frequency increases for and decreases for . Meanwhile, we adopt an integral power number () to solve the orbital equation of photon. The photon's potentials become higher with the decrease of . The behavior of bending light depends on the state parameter sensitively. In particular, for the case of , there is no influence on the deflection of light by quintessence. Else, according to the H-masers of GP-A redshift experiment and the long-baseline interferometry, the constraints on the quintessence field in Solar system are presented here.
