The Internal Rotation of the Sun

Annual Review of Astronomy and Astrophysics, 2003
▪ Abstract  Helioseismology has transformed our knowledge of the Sun's rotation. Earlier studies revealed the Sun's surface rotation, but now a detailed observational picture has been built up of the internal rotation of our nearest star. Unlike the predictions of stellar-evolution models, the radiative interior is found to rotate roughly uniformly ...

Rotation and internal rotation in ArH3+ and ArD3+

Chemical Physics Letters, 1988
Abstract We have developed a semirigid bender model Hamiltonian to calculate the rotation and internal-rotation energy levels of ArH3+ and ArD3+. We have used this Hamiltonian to fit the data reported in M. Bogey, H. Bolvin, C. Demuynck and J.L. Destombes, Phys. Rev. Letters 58 (1987) 988. From the results of the fitting we can predict other rotation

Adiabatic approximations to internal rotation

The Journal of Chemical Physics, 2006
A number of subtle and confusing issues are addressed concerning large amplitude motion (LAM) coordinates (χ) for internal molecular motions, using the methyl rotation in acetaldehyde (CH3CHO) as a model problem. If the LAM coordinate is chosen to be one of the H–C–C–O dihedral angles ρ1, ρ2, or ρ3, it lacks the required 2π∕3 periodicity, and its use ...

Internal rotation in peri-phenylnaphthalenes

The Journal of Organic Chemistry, 1978
A 180o rotation about a phenyl-naphthyl bond is expected to be effectively blocked for derivatives of the peridiphenylnaphthalenes, in which steric requirements force the phenyl rings to assume a face-to-face conformation. However, surprisingly low rotational energy barriers have been found.

Internal rotation in acetone

Journal of Molecular Spectroscopy, 1986
Abstract The geometrical structure of the ground state of acetone obtained by ab initio SCF energies is compared with experimental structures mainly from microwave spectroscopy. The potential function for the internal rotational motions in acetone obtained from SCF energies is compared with experimental.
