Hyper Rayleigh Scattering from DNA Nucleotides in Aqueous Solution

Abstract

Nucleotides are organic compounds consisting of a phosphate group, a nitrogenous base, namely adenine (A), thymine (T), cytosine (C), or guanine (G), and a sugar, here deoxyribose. The magnitude of the first hyperpolarizability  of these four DNA nucleotides were determined in aqueous solution with the nonlinear optical technique of Hyper Rayleigh Scattering under non resonant conditions at the fundamental wavelength of 800 nm. The smallest value is found to be esu for thymidine-5'-monophosphate and the highest is esu for 2'-guanosine-5'-monophosphate. Polarization resolved studies were also performed to question the symmetry of the first hyperpolarizability tensor and access the ratio of some elements of the first hyperpolarizability tensor.
