Electric field effects on reaction centers from Rb. sphaeroides have been detected in ps-transient absorption at 90 K. Upon application of a field of 7 X 10s V/cm the bleaching of the bacteriopheophytin at the A branch (H,, 545 nm) monitored after 30 ps mirrors a reduction of the quantum yield of P+
