Rotational Barrier in Ethylene. It is well known that the rotational barrier of the ethylene molecule cannot be adequately described by a single reference Hartree-Fock calculation SCF calculations on this level resulted in values of 126 kcal/mole (30) and 129 kcal/mole (31) whereas the experimental value is 65 kcal/mole (32). Open-shell ab initio calculations of double zeta+polarization quality give the more acceptable value of 48 kcal/mole (33). Inclusion of correlation such as in CEPA calculations yield theoretical results within the experimental error bar (34), albeit at a considerable computational cost.

The most accurate energies and geometries for the Cl" + CH,Clb system are those calculated at the CEPA-l/avtz and G2(+) levels of theory. Without zero-point energies included, the CEPA- 1/avtz calculations give a complex well depth of-10.6 kcal/mol and a central barrier height of 2.8 kcal/mol. The G2(+) values for these energies are -10.7 and 3.0 kcal/mol. The most recent experimental value for the 0 K complex well depth is 12.2 2 kcal/mol.23...

Only four plant species, i.e., Vicia faba, Allium cepa, Pisum sativum and Triticum turgidum, responded adequately to the Feulgen procedure, and were considered for use in the successive experiments. These species, together with the corresponding mutagenic compounds used and the mutagenicity tests adopted (see below in Sect. 2.4.) are listed in Table 4.
