Crystal Structure of Diamond
IN a recent communication in Nature1, Mrs. Lonsdale has questioned the statement made by Sir C. V. Raman2 that the X-ray data leave the question whether diamond possesses tetrahedral or octahedral
The luminescence of diamond and its relation to crystal structure
SummaryThe relationships which exist between the luminescence of diamond and its behaviour in respect of birefringence are described and illustrated in the paper by a new series of photographs
Structure and Properties of Diamond
THE diamond offers a variety of fascinating problems to the research worker interested in the correlation of physical properties with crystal structure, and the well-known variations of crystalline

On the Relations Between Crystal Counters and Crystal Phosphors
It is shown that all crystals which yield pulses under irradiation with nuclear particles or gamma-rays belong to the class of crystal phosphors. They show luminescence by irradiation in the

THE relationships which exist between the structural symmetry of a molecule and its spectroscopic behaviour have been fully worked out by Placzek1. One result of his theory is that if a molecule has
Experimental evidence for the existence of the four possible structures of diamond
Experimental evidence has been obtained for the existence of the four possible structures of diamond from X-ray and spectroscopic studies. The co-existence of the two variants of the tetrahedral
On the crystal symmetry of diamond and its X-ray reflections
SummaryThe problem of the symmetry of the diamond structure in relation to its X-ray behaviour is considered in a formal manner. It is shown that the presence or absence of the 200 or the 222
XCIII. The hardness properties of cube faces of diamond
Summary Experiments have been made on the abrasion hardness properties of polished cube faces of diamond in directions parallel to the crystallographic axes. Provided the faces coincide with the
X-ray reflection and the structure of diamond
SummaryLaue photographs with the X-ray beam normal to the surface (111) planes have been taken for two typical bluc-fluorescent diamonds exhibiting widely different intensities of fluorescence, but

Raman Spectrum of Diamond.
In the course of an examination of the infra-red and ultra-violet regions of the spectrum of a large number of diamonds, we have come across one which, unlike the others, is transparent both at about
Raman Effect in Diamond.
FROM many points of view diamond is a crystal of supreme interest, and it is remarkable that, though more than two years have elapsed since the discovery of the Raman effect, no attempt appears to

THE eleven years which have elapsed since the first edition of this work appeared, have witnessed a remarkable and welcome increase in the interest taken in crystals by chemists and physicists. On
The Structure of the Diamond
There are two distinct methods by which the X-rays may be made to help to a determination of crystal structure. The first is based on the Laue photograph and implies the reference of each spot on the
Two types of diamond
Among a number of diamonds supplied to us by Professor W. T. Gordon, of King’s College, London, one, by a fortunate chance, was found to differ from the rest in its infra-red spectrum. Having
