Title

Uv Spectroscopy Of Perylene-Co Van Der Waals Complexes

Abstract

A preliminary study of perylene-CO van der Waals complexes has been conducted. The spectroscopy of the major-in-plane and out-of-plane features of the 1:1 and 1:2 perylene-CO aggregates has been analyzed. Little perturbation to the G20 "butterfly" out-of-plane mode is seen in the complex, indicating that the CO moiety may be centered above the perylene plane. An energy shift of -82.5 and -81.9 cm-1 is observed for 1:1 complexes associated with the 000 and A10 modes, respectively, of perylene. An electrostatic perturbation model is used to estimate the ground state well depth and intermolecular separation of 1:1 perylene-CO as D″e = 865 cm-1 and re=3.4 Å. © 1992.
