The van der Waals energy, quadrupole-quadrupole coupling energy, and hydrogen-hydrogen repulsions have been calculated for the equilibrium structure of crystalline naphthalene and for several displaced structures. The displacements are small rotations of the molecules about their symmetry axes, phased so that the space-group symmetry and unit-cell dimensions are preserved. For structural variations of this type the hydrogen-hydrogen repulsions have a strong minimum within a few degrees angular variation from equilibrium, indicating that these repulsions are dominant and determine the crystal structure for this class of displacement. The attractive van der Waals and quadrupole interactions on the other hand are not minimized at the equilibrium structure; they vary slowly (by a few wavenumbers per degree rotation) and approximately linearly.

Internal rotation of a light symmetric top relative to a heavy planar framework: theoretical calculations of vibration/internal-rotation spectra including effects of rotational barriers and non-degeneracy of perpendicular symmetric top vibrations

Model theoretical calculations have been made of the fine structure associated with the perpendicular vibrations of a ‘light’ symmetric top group (such as CH 3 , SiH 3 , etc.) resulting from its internal rotation with respect to an infinitely heavy planar framework. Investigations have been made of the effects on the internal rotational fine structure of the removal of the degeneracy of the perpendicular vibrations as required by the lower site symmetry. Separate calculations have been made for the cases where the removal of degeneracy is caused ( a ) by electronic effects which result in an angular variation of the appropriate force constant, or ( b ) by interaction with another vibration in the framework part of the molecule. It is found that no fine structure lines occur between the non-degenerate frequencies, but that the effect of internal rotation is to generate rotational wings outside this frequency range. The effects of a finite sixfold barrier to internal rotation on the vibrational/internal-rotational absorption band have been calculated for the degenerate and non-degenerate cases. It is shown that certain lines are split by amounts comparable to the barrier height, V 6 , which should therefore be experimentally obtainable from this type of spectrum in favourable cases. The effect of an increasing barrier is to cause more of the intensity within the overall band contour to occur in the vicinity of the vibrational frequency or frequencies, and less in the internal rotational wings, as expected on physical grounds.

Differential Interferometry

Differential Interferometry (DI) combines high spectral and high spatial resolution. On non resolved objects, it yields the angular variation of the source photocenter as a function of wavelength which has been shown theoretically and experimentally to complement very usefully both interferometric and spectroscopic data in a large number of astrophysical problems. This paper presents the general characteristics of DI which are likely to allow improvements of the Doppler images of stellar surface structures as soon as interferometers with large apertures and baselines approaching 100 m are available.

Robotic Belt Grinding

The angular variation of the joints may be large, and collision between workpieces and tools may occur in robotic grinding. Therefore, this paper proposes an optimal robotic grinding path search algorithm based on the recursive method. The algorithm is optimized by changing the position of the tool coordinate system on the belt wheel; thus, the pose of the robot during grinding is adjusted. First, the position adjustment formula of the tool coordinate system is proposed, and a coordinate plane is established to describe the grinding path of the robot based on the position adjustment formula. Second, the ordinate value of this coordinate plane is dispersed to obtain the search field of the optimal robotic grinding path search algorithm. Third, an optimal robotic grinding path search algorithm is proposed based on the recursive method and single-step search process. Finally, the algorithm is implemented on the V-REP platform. Robotic grinding paths for V-shaped workpieces and S-shaped workpieces are generated using this algorithm, and a grinding experiment is performed. The experimental results show that the robotic grinding paths generated by this algorithm can smoothly complete grinding operations and feature a smaller angular variation of the joint than other methods and no collision.

The methods previously described have been applied to a study of the scattering of 6.5 MeV deuterons by deuterium, helium, carbon, nitrogen, oxygen and neon. In the case of deuterium, helium and oxygen the elastically scattered deuterons can be clearly distinguished at all angles of scattering from groups of particles due to other nuclear processes. In experiments with these gases it is thus possible to determine the angular variation of the scattered intensity. The results show that P and D terms make appreciable contributions to the amplitude of the scattered wave. This result is in contrast with that obtained previously in experiments with protons of approximately the same speed, in which it was found that the scattered intensity could be described by an interaction of the Coulomb term with an S -wave only. In experiments with carbon, nitrogen and neon, the peaks in the range distributions due to the elastically scattered deuterons are confused with those produced by protons or α -particles from ( d - p ) and ( d - α ) reactions, and the results are less reliable or are confined to restricted intervals in the angle of scattering. The Q values of the reactions giving rise to the proton groups have been determined and values thus obtained of the energy of a number of excited states in the product nuclei. A study of the variation with the angle of scattering of the range of deuterons elastically scattered by helium nuclei is shown to afford a method of investigating the range-energy relation for an emulsion which has advantages over that previously employed.

The angular variation of the e.s.r. g-value of single crystals of CuSO4,5H2O has been measured in a number of crystal planes. With the assumption that the resonances for each of two independent tensors are symmetrically broadened, the data have been analysed to obtain all the elements of these two tensors. The low value of X (1.27) obtained for the fit to the data indicates that the values obtained for the elements are of worthwhile accuracy. The orientations of the axes of the tensorsin relationship to the Cu-O bond vectors confirm assumptions made in previous treatments. The largest axis of each tensor lies close to one of the Cu-O(SO3) bond directions.
