The Structures Of Fluorene– (H2o)1,2 Determined By Rotational Coherence Spectroscopy, David M. Laman, Alan G. Joly, Douglas Ray

All Faculty Scholarship for the College of the Sciences

Rotational coherence spectroscopy ~RCS!, via time-correlated single photon counting, and two-color resonant two-photon ionization ~R2PI! time-of-flight mass spectrometry, have been used to characterize fluorene–(water)_1,2[FL– (H₂O)_1,2] van der Waals clusters generated in supersonic jets. Rotational coherence traces have been obtained at excitation energies corresponding to several resonant features in the S₁<-S₀ R2PI spectra of FL– (H₂O)_1,2 . RCS simulations and diagonalization of the moment of inertia tensor have been used to obtain S₁ excited state rotational constants and structures of FL– (H₂O)_1,2 that are consistent with …
