Abstract

We have measured resonance Raman spectra, including absolute scattering cross sections, for $I_3^{-}$ in ethanol at eleven excitation wavelengths from 266 to 416 nm, This spectral region spans two broad electronic transitions with dissociate to $I_3^{-}$ + I in the lower energy band and $I_3^{-}$ + I* in the higher energy band.¹ Recent femtosecond experiments by Ruhman and coworkers² have shown that the photodissociation is complex, even though the precursor is only a triatomic.
