The internal rotation of the sun
2008An introduction to current techniques to infer the Sun's internal rotation from observed acoustic oscillation modes is given, and some representative results are shown.

The Journal of Chemical Physics, 1968
Quantum-mechanical calculations within the Hartree–Fock framework and using two Gaussian basis sets are carried out on several conformations of the butane molecule. The smaller basis set predicts a transgauche barrier of 3.536 kcal/mole, an energy difference of 0.822 kcal/mole between the gauche and trans forms, and a barrier of 6.821 kcal/mole for ...

Rotation-internal rotation spectrum of p-fluorotoluene
Journal of Molecular Spectroscopy, 1989Abstract The rotational spectrum of p-fluorotoluene in the vibrational ground state is measured over the frequency range 7–63 GHz. For the lowest torsional state (m = 0), 228 transitions up to J = 30 are assigned and fitted to a rigid rotor Hamiltonian to obtain accurate values of the rotational and five quartic centrifugal distortion constants.

Contributions of Internal Rotation to the Rotational Coefficients in Phenol
The Journal of Chemical Physics, 1968The theory of internal rotation for molecules with twofold barriers is used to calculate the rotational coefficients for phenol using three possible structures. The difference in coefficients for the substates of the ground torsional state is found to be quite dependent upon the structure of the hydroxyl group.

1991
The helioseismic determination of the angular velocity distribution within the sun is discussed. In particular, the bulk of the radiative interior of the sun is rotating at more-or-less the same rate as the photosphere. The latitudinal variation of angular velocity appears to change quite abruptly immediately beneath the base of the convection zone ...

Internal rotation and rotational isomerism in substituted ethanes
Theoretical and Experimental Chemistry, 1967The types of potential energy curves of internal rotation in substituted ethanes were studied. Formulas for the calculation of the energy differences in rotational isomers and of the potential barriers to internal rotation in these derivatives were obtained by Bernstein's method. As a rule, the calculated results are in agreement with experiment.
