In the current investigation, computational viewpoint of doped C20 nano-cage with Zn, Cu+, Ni2+, and Co3+ was described at B3LYP*/6-311G(d,p) level of theory in singlet spin state. Vibrational analysis was established retaining of the optimized nano-cage of the minimum potential energy curve. M-C bond lengths, electronic spatial extent (ESE), photoelectron spectrum (PES) and the results […]
