摘要：

General selection rules for second-harmonic generation in isolated nanoparticles are derived from angular momentum and parity conservation laws. A set of rules is discussed as a function of the particle symmetry group and the polarization of the fundamental wavelength (FW) and second-harmonic fields. A few relevant cases of particle geometry and FW illumination are discussed as examples.
