Experimental observables and macroscopic Susceptibility/Microscopic polarizability tensors for third and fourth-order Nonlinear Spectroscopy of ordered molecular system

摘要: There has been emerging needs for the quantitative polarization analysis Coherent Anti-stokes Raman Spectroscopy and Hyper-raman Spectroscopy, as experimental studies with coherent anti-stokes raman spectroscopy hyper-raman interface membrane being growing. Recently we have demonstrated that orientational of linear nonlinear from ordered molecular system, such interfaces films, can be carried out formulation function in simple functional forms. Applications second order spectroscopy, namely, Second Harmonic Generation Sum Frequency Vibrational helped to understand spectral details films. In employ this higher detailed expressions observables macroscopic susceptibility/microscopic polarizability tensors third fourth-order or film is presented rotational symmetry. General typical fourth Third Generation, degenerated Fourth are their future applications. The advantages limitations spectroscopic techniques also discussed.
