✦ Synopsis
The naphthalene dimer cation was formed on 266 nm nanosecond laser excitation of naphthalene adsorbed in faujasite zeolites at high loading levels and the charge-resonance band of the dimer cation was measured for the first time by use of diffuse reflectance laser photolysis with a near-infrared detection technique. The dimer cations were found to form exclusively inside the cage networks, not at the external surface of the zeolite and are expected to take a twisted form, conformation in which two naphthalene moieties are partially overlapped, enforced by the cage walls.
