The work characterizes the Raman spectrum of the new nano-molecule C 13 H 20 BeLi 2 SeSi / C 13 H 19 BeLi 2 SeSi, nano-molecule Kurumi. Calculations obtained in the methods Restrict Hartree-Fock of the first principles (ab initio), on the set of basis used indicate that the simulated molecule C 13 H 20 BeLi 2 SeSi / C 13 H 19 BeLi 2 SeSi features the structure polar-apolarpolar predominant. The set of basis used that have are correlation-consistent polarized Triple-zeta (CC-pVTZ) and Pople's basis sets six gaussian functions in the shell, three double zeta Gaussian functions, Slater type orbitals with polarization function (6-311G** (3df, 3pd)). In the CC-pVTZ base set, the charge density in relation to 6-311G** (3df, 3pd) is 50% lower. The length of the molecule C 13 H 20 BeLi 2 SeSi is of 15.799Å. The Raman spectrum was calculated indicating the characteristic of the nano-molecule and their frequency (cm -1 ) were obtained in the set of bases used. The highest for Raman scattering activities peaks are in the frequency 3,348cm -1 with 7.107609729Å 4 /amu and 2,163cm -1 with 8.902805583Å 4 /amu, for CC-pVTZ and 6-311G** (3df, 3pd), respectively. As the bioinorganic molecule C 13 H 20 BeLi 2 SeSi is the basis for a new creation of a biomembrane, later calculations that challenge the current concepts of biomembrane should advance to such a purpose. The new nano-molecule Kurumi is well characterize computationally. As its scientific name 3-lithio-3-(6-{3-selena-8-beryllatricyclo[3.2.1.0², 4 ]oct-6-en-2-yl}hexyl)-1sila-2-lithacyclopropane.
