Abstract
The potential energy surface of the tetrahydropyrane ... HCl system was exp lored at the MP2/6-31G(d,p) level of theory. The computed geometries for th e axial and equatorial conformers agree rather well with the experimental d ata from microwave spectroscopy. The QCISD(T)/6-31G(d,p)//MP2/6-31G(d,p) st abilization energies for the two conformers are rather similar. Further the oretical analyses suggest that the axial conformer should be slightly more stable. (C) 2000 Elsevier Science B.V. All rights reserved.
