摘要：
Relative energies (by MP4(SQTQ)/def2-TZVPP) for 13 tautomeric conformers of 5-chlorouracyl in the gas phase and in solution with consideration of nonspecific solvation in water are calculated. The geometrical parameters of the calculated conformers are analyzed. A stability series of tautomers with respect to the diketo form is obtained. It is shown that nonspecific solvation leads to changes in the stability series.
