Abstract : DNA polymer in dilute aqueous solution responds to external illumination. Because it is charged system surrounded by another charged syste, counterions, it interacts strongly electromagnetically. We find that a normal mode may exist in the form of a one dimensional plasmon, analogous to the three dimensional plasmons well known in metal physics and the two dimensional surface plasmons of surface physics of conductors. The DNA plasmon frequency is proportional to the excitation wave number, i.e. the first power, in contrast with the one/half power for surface plasmons and the zero power for bulk metallic plasmons. Keywords: Resonance, microwaves; Water; Hydration; Polymers; Molecular structure. (aw)
