Rydberg atoms are extremely sensitive to electric fields and consequently have a rich Stark spectrum. We present measurements and numerical calculations of Stark shifts for Rydberg states of 87Rb. We extended the numerical method of [M. Zimmerman et al., Phys. Rev. A 20, 2251-2275 (1979)] to allow for a calculation of the transition strength from low lying states to Stark shifted Rydberg states. The results from these calculations are compared to high precision measurements of Stark Maps for Rubidium Rydberg atoms with principal quantum numbers up to 70 and electric fields ranging beyond the classical ionization threshold. An electromagnetically induced transparency measurement scheme is used to detect Rydberg states inbetween two electrodes of a capacitor in a glass vapor cell.
