Second harmonic generation principals

Second harmonic generation of (NH4)5Nb3OFi8,233 K5Nb3OF g, 233 Li4Nb04F, 226 Li4Ta04F, 229 other compounds, 225 principals, 224 Rb5Nb3OF18,233 temperature dependence, 226,229... 

The fundamentally important case p-nitroaniline (PNA), the high symmetry parent molecular unit of MNA, presents an excellent example for both experimental methodology and theoretical analysis. In the C 2 v symmetry for PNA and second harmonic generation, the measured principal component 3X is given by... 

Another line of research has been to assemble complex optical structures with exquisite precision examples are the work of Kuhn and Mobius on resonant energy transfer involving dye molecules" and second-harmonic generation, the principal requirement of which is a non-centrosymmetric structure, readily achievable using the LB technique.
