Statistical analysis of second harmonic generation experiments: a phenomological model

Welsh, Alan; Mansson, R A; Frey, J G; Danos, L

Description

We discuss issues arising in fitting theoretically derived nonlinear models with complex coefficients to data from surface Second Harmonic Generation (SHG) experiments conducted at the air/liquid interface. We explore different parametrisations for the complex parameters and show that the Euler (magnitude and phase angle) parametrisation is preferable to the real and imaginary parts parametrisation, both theoretically and empirically. We emphasise the importance and value of diagnostic plots...[Show more]
