Some C-56 isomers obtained theoretically from C-60 structure by deleting two C-2 units and bonds adjacent to those have been subjected to AM1 (UHF) type semiempirical quantum chemical calculations. Positional effects of dodecagonal (cyclododecahexaene rings) holes on the stabilities are discussed in the case of neutral as well as monovalent cationic form of these species which are all stable but endothermic in nature.

The ortho- to meta- isomerization of dicarba-closo-dodecaborane
Türker, Burhan Lemi (Elsevier BV, 2003-08-01)
By means of AMI(RHF) type semiempirical quantum chemical calculations, the conversion of ortho- dicarba-closododecaborane to its meta- isomer is throughly investigated by considering two intermediate structures previously proposed.
The electronic structure of GanPm(n+m = 5, 17, 29, 35), Ga13P4 (in SiO2) and Ga13P4 (in sodalite) clusters
Katırcıoğlu, Şenay (Elsevier BV, 2004-12-31)
The electronic structure of optimized GanPm(n+m=5, 17, 29, 35) isomers and Ga13P4 cluster in SiO2 matrix and sodalite cage has been studied by Hartree-Fock theory to find out the effect of cluster size and Ga-O bonds on the optical energy gap between LUMO and HOMO. It was found that the optical energy gap of Gal? clusters can be regulated by both the cluster size and the Ga-O interface satisfied by either SiO2 matrix or sodalite cage. The energy gap between LUMO and HOMO of Ga13P4 (in sodalite) cluster has ...
Theoretical investigation of hydroxytyrosol and its radicals
Erkoc, F; Keskin, N; Erkoç, Şakir (Elsevier BV, 2003-05-05)
The structural and electronic properties of hydroxytyrosol, its three radical isomers, and its three analogues hydroxytyrosol-dihydroxyl isomers have been investigated theoretically by performing semi-empirical self-consistent field molecular orbital theory calculations. The geometry of the systems have been optimized and the electronic properties have been calculated at the level of AMI method.
Possibility of cyclic transition states of nitroglycerine
Türker, Burhan Lemi (Elsevier BV, 2004-07-26)
The possibility of six-membered cyclic transition states involving the oxygen atom of a nitro group of nitroglycerine molecule and the hydrogen atom at the a-position to the nitro group considered is investigated quantum chemically by using AMI (UHF) type semiempirical calculations. The results indicate that such kind of structures are stable and exothermic in nature.
A theoretical study on a fullerene derivative C54N4 and some of its protonated forms
Türker, Burhan Lemi (Elsevier BV, 2004-07-05)
Semiempirical quantum chemical calculations at the level of AMI (restricted Hartree-Fock) have been performed on a fullerene derivative, C54N4, theoretically obtained from C-60 and its mono and diprotonated forms. All these structures are stable, but endothermic in nature. Some calculated geometrical and physicochemical properties of these have also been reported.
