ISSN: 0377-0486Keywords: Chemistry ; Analytical Chemistry and SpectroscopySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyPhysicsNotes: This paper is concerned with the automation and control of grating spectrometers by digital techniques. The methods outlined include: a simple manually operated digital control; a dedicated logic system with data storage; data acquisition and control systems run by a computer in real-time and time-sharing modes. The performance of these methods is evaluated. A basic spectrometer control unit is described; this unit forms a module around which more general spectrometer control systems may be constructed.Additional Material: 9 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0377-0486Keywords: Chemistry ; Analytical Chemistry and SpectroscopySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyPhysicsNotes: The oriented gas model of the polarisability of a molecular crystal provides a basis for the discussion of its Raman spectrum. This model is examined with a view to deriving information about eigenvectors of the zone centre lattice vibrations in these crystals. The theory of the general case is much simplified by symmetry conditions in certain instances. This is applied to the molecular crystal perfluorobiphenyl, C12F10, of recent interest. For this crystal it is found necessary to extend the theory to include the coupling of internal vibrations with the lattice vibrations. A simple model is found to account for this and the extent of the coupling is thereby estimated.Additional Material: 11 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0377-0486Keywords: Chemistry ; Analytical Chemistry and SpectroscopySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyPhysicsNotes: This paper describes a simple numerical method for the smoothing and differentiation of digitally collected Raman spectra. This is applied to a peak finding program suitable either for batch processing of data or real time application with a computer controlled spectrometer. A basis for the implementation of such programs is given, and their limitations are discussed.Additional Material: 6 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0377-0486Keywords: Chemistry ; Analytical Chemistry and SpectroscopySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyPhysicsNotes: The Raman spectrum of orthorhombic sulphur has been measured in the frequency range 0-100 cm-1 for all polarisations. The A1g(zz) and B1g(xy) spectra have been clarified by later subtraction of unwanted scattering belonging to other polarisations. Definite assignments are made for all but one A1g and one B2g mode. An interpretation of the intensities observed in the A1g and B1g spectra is given in terms of the rotational motion of the S8 molecules affecting their contribution to the crystal polarisability.Additional Material: 5 Ill.Type of Medium: Electronic ResourceURL:
