dc.description.abstractDiethylaniline (DEA) exhibits prominent low frequency activity in its vibrationally resolved $S_{1} \leftarrow S_{0}$ fluorescence excitation spectrum. We report here studies at full rotational resolution of the first three hands in this spectrum which appear within $200 cm^{-1}$ of the origin. The spectra yield rotational constants of the $S_{0}$ and $S_{1}$ states, from which it is shown that the inertial defect $(|\Delta I|)$ increases on $S_{1} \leftarrow S_{0}$ excitation, that $|\Delta I|$ increases with increasing vibrational energy in the S1 state, and that the orientation of the $S_{1} \leftarrow S_{0}$ transition moment is a function of excitation energy, as well. We will deduce from these results and related theoretical calculations the preferred conformation of DEA in its $S_{0}$ and $S_{1}$ states, the nature of the vibrational modes that appear in the $S_{1} \leftarrow S_{0}$ spectra, and the possible relevance of this motion to the TICT character of the $S_{1}$ states of aniline, DEA, diethylaminobenzonitrile (DEABN), and related molecules.en_US
