The Liquid Density of Complex Liquid Mixtures
A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from Ttp to T<su...
متن کاملRaman spectra of dipicolinic acid in crystalline and liquid environments.
Raman spectra of dipicolinic acid (DPA) are important for detection of bacterial spores, since DPA and its salts present one of their major components. The implementation of a deeply cooled CCD camera in combination with pulsed excitation at 532 nm allowed measuring well-resolved Raman spectra of the DPA in different forms. Powder preparations, crystals grown from saturated solutions and aqueou...

متن کاملFT-Raman Spectra of Saffron (Crocus Stivus L.); A Possible Method for Standardization of Saffron
FT-Raman Spectra of Saffron (crocus sativus L.) with a partial assignment is reported. Based on the Raman data, it is concluded that main pigments in saffron are crocins and crocetin. It is proposed that the quickly attainable FT-Raman spectrum of solid saffron, may be used as a means of saffron standardization.
متن کاملCalculations of nonlinear spectra of liquid Xe. II. Fifth-order Raman response
The polarization dependence and temporal profile of the fifth-order Raman response function and corresponding correlation function in liquid Xe are studied both analytically and numerically. Based on the symmetry of an isotropic sample, the fifth-order Raman response function has twelve distinct tensor elements, ten of which are independent, and the corresponding correlation function has twelve...
