The molecular simulation was performed to optimize molecular structures of DMTSF, DMTTF, TMTSF and TMTTF. IR and Raman spectra of these molecules at optimum state were also computed. Raman spectra at different temperatures and at different exciting frequencies were also computed. NBO analysis was performed to study second order interaction and HOMO-LUMO energies and their gap. The orbital energy and occupation with complete NBO of Lewis and non-Lewis orbit were also computed.
