    Abstract: A method for mapping the crystal structure of a diamond comprises placing the diamond in a beam of monochromatic laser radiation, filtering the resultant scattered Raman radiation, and measuring the intensity of the filtered radiation at one or more different orientations of the diamond. The intensity may be recorded to produce a record of the diamond which may be compared with records of known diamonds to identify the diamond.

    Abstract: A method for assessing diamonds of different quality characteristics in which a laser Raman spectrometer is initially calibrated by use of diamonds of known quality characteristics, the characteristics having been assessed for example by a conventional subjective procedure. Diamonds of unknown quality characteristic are successively placed in the spectrometer and irradiated with laser radiation of known frequency. The intensity of the scattered Raman signal from the diamond of unknown quality is monitored for one or more orientations of the diamond, the resultant signal being capable of relation to the quality of the diamond.

    Abstract: Mass flow of a multi-phase fluid is determined by feeding the fluid into a chamber through a positive displacement device and measuring the density of the fluid. The fluid is removed from the chamber at the same volume rate as that at which it is introduced. The density of the fluid in the chamber is measured together with the number of volume increments passed.

    Abstract: A process for the preparation of an ester of dicarboxylic acid from an alkene, carbon monoxide. The process is catalysed by a catalyst which comprises a platinum group metal, for example palladium, and a copper compound. To avoid catalyst deactivation the process is carried out in the presence of a dihydrocarbyl peroxide which is reduced to a hydrocarbyl alcohol under the process conditions. The process can be used, for example, to prepapre succinate esters from ethylene, carbon monoxide, an alcohol and a dihydrocarbyl peroxide such as di-tertiary butyl peroxide.
