Non resonant interaction of laser light with conjugated macromolecules in macroscopic quantum state
is first order nonadiabatic process.


1. Conjugated polymers with macroscopic quantum properties show abnormally high intensity of overtones and combinations at non resonant excitation of Raman scattering.
2. For conjugated polimers in macroscopic quantum state there is only small difference in intencity of resonant and non resonant Raman scattering.
3. We suppose that non resonant interaction of laser light with conjugated macromolecules in macroscopic quantum state is first order nonadiabatic process.
4. Below (figure c) you can see Raman Scattering spectra of film of nanopolyacetylene, which was synthesized at Re catalyst.


Example
Raman spectra of NPA


Fig. (c) Raman scattering spectra of film of nanopolyacetylene using six laser lines from blue (488 nm) to near infrared (1064 nm). For all laser lines excitation energy is less than 10 mW.

One can see from figure (c) that for all excitation energies (including non resonant excitation) relative intensity of overtones and combination bonds of (C=C) and
(C-C) stretching modes, corrected to wavelength dependence of the Raman scattering, commensurable with intensity of fundamentals.
