Resonant Raman scattering and hot luminescence of anthracene in the region of exciton absorption
Aaviksoo Ya.Yu., Saari P.M. , Tamm T.B.
The spectrum of resonant secondary luminescence at the bottom of the S, absorption band was measured for the first time. The hot lines attest to the presence of a quasibound phonon of internal frequency ν = 395/cm ~ l. With the exciting light polarized along the a-axis of crystal the Raman scattering lines assume shapes that fail to conform to elementary treatment.
