Opis:: The geometry of spiropyran molecule and its derivatives was found using quasi-Newton methods, Broyden-Fletcher-Goldfarb-Shanno technique. Then ab initio quantum chemical methods were applied to calculate the ground state energies of the closed and open forms of spiropyran for different basis sets. The frequency dependent linear polarizability of spiropyran and derivatives were obtained and plotted. The found absorption peaks are different for the closed and the open structures of the spiropyran molecule.

Opis:: A static magnetic field B$\text{}^{0}$, acting on a chiral liquid perpendicular to the propagation direction of an optical beam, is shown to induce a magnetochiral change of Rayleigh light scattering which is different in sign for the light scattered parallel and antiparallel to B$\text{}^{0}$. It is related to the electric dipole and magnetic dipole or/and electric quadrupole moments induced simultaneously in a chiral molecule by electric dipole interaction with electromagnetic radiation. For diamagnetic molecules the effect is described by linear and nonlinear polarizabilities, responsible also for circular birefringence (natural optical activity and the Faraday effect) as well as axial (magnetochiral) birefringence.

Opis:: Precise values for electric dipole moments of isolated acetone and acetic acid molecules were determined from the Stark effect measurements made on lowest J rotational transitions at conditions of supersonic expansion. The new results are $μ_{tot} =μ_b$ =2.9345(22) D for acetone from measurements on the $1_{11}$← $1_{01}$ transition, and $μ_a$ =0.8631(8), $μ_b$ =1.4345(11), $μ_{tot}$ =1.6741(10) D for acetic acid, from measurements on $1_{11}$ ← $0_{00}$ and $1_{01}$ ← $0_{00}$ transitions. A comparison with previous determinations and with results of quantum chemical calculations is presented.
