Topological indices are numerical values associated with chemical constitution describing the structures of chemical compounds and helping to predict different physicochemical properties. In this report, some newly designed topological descriptors, namely, neighborhood Zagreb index (M_N), neighborhood version of Forgotten topological index (F_N), modified neighborhood version of Forgotten topological index (F^*_N), neighborhood version of second Zagreb index (M^*₂), neighborhood version of hyper Zagreb index (HMN) are obtained for the TU RC₄C₈(S), armchair nanotube TU AC₆, V-phenylenic nanotube V PHX[m; n], and V-phenylenic nanotori V PHY [m; n].

Keywords: Topological indices, TURC4C8(S), armchair nanotube (TUAC6), V-phenylenic nanotube (V PHX[m; n]), V-phenylenic nanotori (V PHY [m; n]).
