Comparison of the Stark spectrum and the second derivative of the absorption spectrum (SDS). (A) The Stark spectrum (solid line) and SDS (dotted line) measured at 77 K (26). (B and C) The calculated Stark spectra (solid line) and SDS corresponding to calculated OD (dotted line). The calculated data is obtained with the Inline graphic configuration of the CT state. The Stark signal is calculated with the CT static dipole of 30 D (C) and 0 (B).
