摘要：

The results on the excited-state kinetics and thermodynamics of adiabatic conformational interconversion in centrosymmetrical disubstituted napthalenes when dissolved in 3-methylpentane (3-MP) and in a more viscous hydrocarbon hydrocarbon tetradecane (C14) were presented. X-ray crystallography proves that the almost planar cis configuration of 2-methoxynaphthalene is the energetically favorable form in the ground state. The exocyclic link is found to be a double bond with a length of 1.366Å, which is significantly shorter than a single C-O bond length of 1.43366Å in methyl ether. Quantum conformational calculations including RHF and DFT theory also support the conformational preference of the cis isomer of the reference compound 2-methoxynaphthalene.
