In his laboratory at Argonne, Dietrich has been leading a project to measure an important property (the 'electric dipole moment') of radium atoms after they have been laser cooled to a temperature just slightly above absolute zero.
In ferroelectric materials, these electric dipoles exist at the unit cell level and give rise to a non-vanishing permanent electric dipole moment.
Quantum chemical parameters for synthesized molecules (2a, b) such as the energy of the highest occupied molecular orbital (EHOMO), the energy of the lowest unoccupied molecular orbital (ELUMO), HOMO-LUMO energy gap (IE), chemical hardness (), softness (I), electronegativity (X), chemical potential (u), dipole moment (DM), global electrophilicity (I), sum of the total negative charge (TNC) and sum of electronic and zero-point energies (SEZPE) for gas and solvent phase of neutral molecules were calculated and discussed.
More recently, in [24], the authors succeeded to solve the eigenvalue wave equation for an electron in the field of a molecule with an electric dipole moment by expanding the solutions of a second-order Fuchsian differential equation with regular singularities in cos [theta] = 1,-1,0 in a series of Jacobi polynomials with "dipole polynomial" coefficients.
The dipole moment ([mu]), linear polarizability ([alpha]), anisotropy of the polarizability ([DELTA][alpha]), and first hyperpolarizability ([beta]) are important factors of nonlinear optical (NLO) properties, and [beta] is defined as the third derivative of the total energy.
