N2 - The two-photon resonant Raman scattering (TRRS) process via the excitonic molecule (EM) state in red-HgI2 is studied at 1.6 K. The intensity of the TRRS line is enhanced with FWHM 0.7 meV at 2.3324 eV which corresponds to a half of the EM energy. From the analysis of the TRRS data, the dispersion curve of the transverse exciton polariton is determined: The transverse exciton energy and its effective mass relative to the electron rest mass are obtained as 2.3348—0.0001 eV and 1.3 —0.1, respectively. The background dielectric constant, ∊¥, is determined to be 10.5 —0.5 from the Fabry-Perot interference fringes of a thin single crystal.
