    • The configurations of the isomers were generated and the energies were subsequently minimized using the MM+ force field which is implemented in release 3.0 of HyperChem®. MM+ supplements the standard MM2 parameters (N. L. Allinger, J. Am. Chem. Soc., 99, 8127 (1977)). The minima obtained from the search were further optimized using the AMI wavefunction, M. J. S. Dewar, E. G. Zoebisch, E. F. Healy and J. J. P. Stewart, J. Am. Chem. Soc., 107, 3902 (1985) and the RHF approximation.
