The linear absorption spectrum and resonance Raman spectrum of a
series of charge-transfer molecules in solution are measured. The results
are fitted to theoretical expressions. The dispersion of the first hyper-polarizability
is investigated by substituting the parameters, which are obtained from
the fit. The results are compared with Wang's formula
modified from the simple Oudar and Chemla two-level model. The
resonance Raman spectra and Raman profiles show that only one excited
state exists in two of the charge-transfer molecules and two excited states
are present in three other molecules investigated in this expeariment. It is
concluded that Wang's modified formula is only valid to account for the
dispersion of the first hyperpolarizability when there is only one excited
vibronic state.
