Spectroscopic evidence for strong oscillating and static dielectric polarizations in malignant cells.
Analysis of splitting and shifting of malignant cell (mammary carcinoma and virally transformed cells) Raman and microwave spectral lines suggests that the Raman line splittings are due to non-linear second-order coupling of a coherently excited optical polarization wave with other polarization modes within these malignant cells. The microwave splittings are believed due to the non-linear second-order coupling effects of a lower frequency acoustic wave. The spectral line shiftings are believed indicative of a strong static dielectric polarization (ferroelectric state) of the cells.
