The low surface rotation rate of the Sun and other main-sequence stars is believed to be the result of angular momentum loss due to a stellar wind1. This loss also leads to a differential rotation, the interior spinning more rapidly than the surface. The rate of increase with depth of the rotation speed is limited by hydrodynamic instabilities, which ...

The Journal of Physical Chemistry B, 2023
Measurement of molecular orientation relaxation using ultrafast infrared (IR) pump-probe experiments is widely used to understand the properties of liquids and other systems. In the simplest situation, the anisotropy decay is a single exponential reflecting diffusive orientational relaxation.

Nature, 1984
The frequency difference between prograde and retrograde sectoral solar oscillations is analyzed to determine the rotation rate of the solar interior, assuming no latitudinal dependence. Much of the solar interior rotates slightly less rapidly than the surface, while the innermost part apparently rotates more rapidly.

Internal rotation in acetaldehyde
Journal of Molecular Spectroscopy, 1976Abstract The microwave spectrum of acetaldehyde has been investigated in the frequency range from 7 to 40 GHz. A rather complete assignment of rotational transitions in the ground and torsionally excited states has been found with the help of microwave-microwave double resonance techniques.

The Internal Rotation of the Sun
1986Recent results on the internal rotation of the sun are difficult to explain. These problems are reviewed and it is conjectured that a 3He driven mixed shell near 0.3R⊙) magnetically separates the inner core from the outer regions. Such a shell may rotate differentially and may separate a more rapidly spinning core from the rest of the sun.

Rotation—internal rotation—vibration interaction in nitroethylene
Chemical Physics, 1974Abstract Rotation—internal rotation and vibration interaction in the nitroethylene molecule is analyzed by four different approaches: rotation—internal rotation theory without and with inclusion of the CH out-of-plane bond bending mode, rotation—internal rotation theory with inclusion of structure relaxation of the NO 2 group, and conventional ...

Rotational spectrum, structure and internal rotation in CH3CCl3
Journal of Molecular Spectroscopy, 2008Abstract The rotational spectra of the v 6 = 1 and v 6 = 2 torsional states of CH 3 C 35 Cl 3 have been measured in the millimeterwave range and accurate spectroscopic constants have been determined. The equilibrium structure, the torsional frequency and the barrier to internal rotation have been calculated ab initio.

Rotation and internal rotation in the vinyl cation C2H3+
Journal of Molecular Spectroscopy, 1987Abstract In the vinyl cation C 2 H 3 + it is believed that there is a low barrier hindering the rotation of the three protons around the CC core, with the molecule remaining planar during this internal rotation. In this paper the semirigid bender formalism is adapted to calculate the rotation and internal-rotation energy levels of this species ...

On Polytypism and Internal Rotation
The Journal of Chemical Physics, 1969The ordered stacking of eclipsed (E) and staggered (S) layers in SiC or ZnS crystals leads to formation of polytype lattices. The short-range forces acting between layers are considered to be analogous to those determining the barriers to internal rotation in molecules. This is applied to an understanding of eclipsing in covalent lattices (SiC, diamond)
