Abstract.
The theoretical formalism of local density approximation (LDA) to density functional theory (DFT) has been used to study the electronic and geometric structures of SimCn + (1≤m, n ≤4) cationic clusters. An all electron 6-311++G** basis set has been used and complete geometry optimizations of different possible structures for a specific cluster have been carried out. Binding energies, relative energies, fragmentation energies, vibrational frequencies, and adiabatic ionization potentials of the optimized clusters have been investigated and reported in detail. Results have been compared with other experimental and theoretical results available in the literature.
