Title: Resonance Raman Effect And The Structures Of The Naphthalene-tetrahalophthalic Anhydride π-complexes In The Triplet State
Author: Caetano C.A.
Abstract: The triplet state properties of the naphthalene-tetrachlorophthalic (N:TCPA) and naphthalene-tetrabromophthalic (N:TBPA) anhydride π-complex crystals were studied at room temperature using the resonance Raman technique. The RR effect was observed in the triplet charge-transfer states of the two complexes. The heavy-atom effect and charge-transfer complexation are the dominant factors leading to intensity enhancement of donor and acceptor vibrational modes. The relationship between the effect in the complexes and the parent molecules provides evidence for different structures for N:TCPA and N:TBPA in the triplet state. Most probably the N:TCPA complex has the two planar components colinear, with the molecular planes parallel along the molecular axis. The N:TBPA complex probably has the two components bound in such a manner the carbon-bromine bonds are distorted out-of-plane. © 1989.
