β¦ Synopsis
Since its synthesis by Vogel et al., 4 1,6loethano[lO]annulene has been subjected to extensive Investigation to explore Its reactivity and aronaticity. We report here the results of a.b initti, CNDO/Z, and INDO molecular orbital (MO) calculations on this molecule.

We report a high quality gaussian orbital calculation on the benzyl, anilino and phenoxyl radicals. We have also calculated the ESR hyperfine coupling constants for these radicals and find reasonably good agreement with experiment.
## Abstract Optimized geometries and total energies for the conformers of 3,6βdihydroβ1,2βdithiin (2) and 3,6βdihydroβ1,2βdioxin (3) were calculated at several __ab initio__ MO levels: RHF/3β21G(\*), RHF/6β31G\*, MP2/6β31G\*, and MP2/6β31G\*/ /RHF/3β21G(\*). For the dioxin, in addition to the above
