We report, till date the highest value of molecular first hyperpolarizability (Second order Nonlinear Optical response) for an organic molecule. Calculation shows that low energy absorption (Far-IR) and large ground to excited state dipole difference, are mainly responsible for such a high value first hyperpolarizability even at the molecular level.
