M. Lequan et al., HYPERPOLARIZABILITY OF TETRAORGANOTIN COMPOUNDS DETERMINED BY THE HYPER-RAYLEIGH SCATTERING TECHNIQUE, Chemical physics letters, 229(1-2), 1994, pp. 101-104
The hyperpolarizability of non-polar tetraorganotin molecules with T-d
symmetry has been investigated by the hyper-Rayleigh scattering techn
ique. The results show that, in spite of the absence of a dipolar cont
ribution to the hyperpolarizability tenser, the value of beta is signi
ficantly high.
