Polarized Raman spectra (785-nm excitation) of an aqueous solution of ethidium bromide (1.6 mg/mL in 100 mM NaCl, pH 7, 20°C). Perpendicular and parallel polarizations are indicated by I⊥ and I‖, respectively. The inset at left shows corresponding polarized Raman spectra of liquid CCl4 (175–600 cm−1 region) to illustrate the accuracy of depolarization measurements.
