Figure 4.

Figure 4

S0 (11Ag–) → S2 (11Bu+) and S1 (21Ag–) → S0 (11Ag–) transition energies of dimethylpolyenes in nonpolar, room temperature solutions as a function of polarizability, R(n) = (n2 – 1)/(n2 + 2). Squares represent the (0–0) bands of the S0 (11Ag–) → S2 (11Bu+) transitions; diamonds represent the (0–0) bands of the S1 (21Ag–) → S0 (11Ag–) transitions. S0 → S2 transition energies for gaseous decatetraene (in air and in vacuum) and for dodecapentaene (in air) are shown as circles. Uncertainties in the plotted values are given in Table 1 and are either comparable to or smaller than the size of the symbols in the figure. Parameters derived from linear, least-squares fits of the data are given in Table 3. Transition energies in air and vacuum were not included in the linear fits.
