Theoretical calculations and vibrational potential energy surface of 4-silaspiro(3,3)heptane

Abstract: Theoretical computations have been carried out on 4-silaspiro(3,3)heptane (SSH) in order to calculate its molecular structure and conformational energies. The molecule has two puckered four-membered rings with dihedral angles of 34.2° and a tilt angle of 9.4° between the two rings. Energy calculations were carried out for different conformations of SSH. These results allowed the generation of a two-dimensional ring-puckering potential energy surface (PES) of the form V = a(x1 (4) + x2 (4)) - b(x1 (2) + x2 (2))… Show more

“…More recently, we reported the two-dimensional PES for the two ring-puckering vibrations of 4-silaspiro [3.3]heptane (SSH). 18 The calculated quantum states, wave functions, and predicted spectra were reported. For SSH, the PES has the form of eq 1 but does not require the x 1 x 2 term.…”

“…The complex nature of the ring-puckering quantum states and the resulting spectra were analyzed in detail. More recently, we reported the two-dimensional PES for the two ring-puckering vibrations of 4-silaspiro[3.3]heptane (SSH) . The calculated quantum states, wave functions, and predicted spectra were reported.…”
