Abstract
Abstract—Laser flash photolysis studies of DNA‐complexed ethidium bromide were undertaken. We have observed a singlet‐singlet (S1‐Sn) absorption process for DNA‐complexed ethidium bromide. The observed lowest singlet excited state lifetime was 21 ± 2 ns. The molar difference extinction coefficient was measured to be 2.4 ± 0.4 × 103M‐1cm‐1at 370 nm. The assignment of this transition was confirmed by time resolved fluorescence measurements.This publication has 9 references indexed in Scilit:
