The transition oscillator strengths, transition rates, and wavelengths for electric dipole transitions between 1s2s2p2np 6Po (n=3-9), and 1s2s2p2n's, 1s2s2p2n'd 6Pe (n=3-5) sextet Rydberg states of boron-like S ion are calculated using the multi-con?guration Rayleigh–Ritz variationmethod. The transition rules for 1s2s2p2np 6Po Rydberg series of S11+ ion are disscussed. Our calculated results will provide useful data for the related experimental study in the future.
