Vibrational hyperpolarizability of SF&
Expressions are derived for the vibrational second hyperpolarizability 1'" of SF 6' in the static limit and for the nonlinear-optical processes of the dc Kerr effect, electric-field-induced second harmonic generation (ESHO), and third harmonic generation (THO). These expressions give 1'" in terms of vibrational transition dipole, polarizability, and first hyperpolarizability matrix elements (f-...
متن کاملMeasurement of Second Hyperpolarizability and Nuclear Rotational Response of Gas-phase Carbon Disulfide
We use nonlinear beam deflection to separate the bound-electronic and nuclearrotational responses in gas-phase CS2. This allows a direct comparison of the second hyperpolarizability to our liquid CS2 measurements considering local-field effects. OCIS codes: (190.0190) Nonlinear optics, (190.3270) Kerr effect, (190.5650) Raman effect, (350.3250) Isotope separation
متن کاملCrystal structure of dibenzoyl diselenide.
C14H10O2Se2 is monoclinic, P2(1)/c. The unit-cell dimensions at 293 K are a = 12.795(2), b = 12.126(2), c = 9.0179(13)A, beta = 107.074(6)degrees, V = 1337.5(3)A3, and Z = 4. The R value is 0.048 for 2319 observed reflections. The dihedral angle between the plane C4-C7(O2)-Se1 and C9-C8(O1)-Se2 is 85.6(2)degrees, keeping the Se atom unshared electron pairs in a more stable configuration with th...
متن کاملSaturation of the second hyperpolarizability for polyacetylenes
Polyacetylene (PA) polymers -(-CH=CH-), lead to large second hyperpolarizabilities (y) that increase with N. For small N the increase is quite rapid, eventually saturating (becoming linear in N) for N > N& Both experimental and theoretical attempts have been made to estimate N,Y,,. In 1994 this led to two Science papers, one obtaining NA, = 20 (semiempirical theory) and the other obtaining N,,,...
متن کاملOn the Hyperpolarizability of the Lithium Dimer
All independent components of all electric polarizability and hyperpolarizability tensors up to the fourth rank have been calculated near the Hartree-Fock limit for L i2(l a 2 l a l 2 a l , X l 27+). Many of the molecular properties reported in this paper appear for the first time in the literature. Our values for the isotropic components of the C, B and y hyperpolarizabilities are 1487 e2 öo E...
