“Nutation” of electron spins in biradicals

Journal of Magnetic Resonance
In this work, the nutation of the spins of unpaired electrons in the nitroxide biradical of bis‑methano[60]fullerene was experimentally studied. Nutation frequencies were found in a wide range of microwave field power. To interpret the obtained results, numerical calculations of the nutation of biradicals were carried out for a set of parameters of the

Nutations Of The Earth

Annual Review of Earth and Planetary Sciences, 1992
The figure of the Earth is very nearly that of an oblate spheroid. Its moments of inertia about principal axes in the equatorial plane differ from each other only by about two parts in 105, and may be taken to have a common value A, for the purposes of nutation theory.

Comparison Between the Nutations of the Planet Mars and the Nutations of the Earth

Surveys in Geophysics, 2000
The nutations of the planets Mars andEarth are investigated and compared. Alarge number of interior structureparameters are involved in the nutationcomputations. The comparison between the observations and the computationsprovides several constraints on these parmeters andtherefore allows a better understanding of the physics of the interior of ...

Residual nutation angle of satellites with viscous nutation dampers

Acta Astronautica, 1987
Abstract The residual nutation angle of satellites with the viscous fluid dampers is one of the important indexes for designing the spinning satellites of high nutation precision. This paper will specifically discuss the reasons why the viscous dampers make the residual angle occur.

Nutation in Plants

2007
This chapter aims to explore and describe the physiological aspects of oscillating growth patterns in rapidly elongating plant organs, such as roots, hypocotyls , shoots, branches and flower stalks. After a brief description of the phenomena, the theories and models proposed to explain circumnutation are reported, focusing largely on the internal ...

A search for free core nutation modes in VLBI nutation observations

Physics of the Earth and Planetary Interiors, 1995
Abstract In recent decades much effort has been devoted to searching observations for evidence of free core nutations predicted by theoretical models. Polar phototube data, tidal gravity observations and very long baseline nutation measurements have all been used.
