✦ Synopsis

Unpolarized Raman spectra of were measured at room temperature in the range 20-1100 cm-1 and are Pb 5 MoO 8 discussed in terms of two structural models, one based on electron di †raction data and the other on x-ray di †raction data, which di †er in the proposed arrangements of Mo atoms. The validity of the two models was tested by comparing the experimental Raman spectrum of with the calculated spectra for clusters typical of the Pb 5 MoO 8 two models. It is shown that the experimental Raman spectrum is Ðtted very well by Raman-active modes of the structural units based on x-ray di †raction data, pointing to the correctness of the x-ray di †raction model. 1998

Acetone-phenol mixtures with phenol mole fractions in the range 0.079-0.6000 were studied by Raman spectroscopy. Spectra were obtained in the regions of acetone CxO stretching and C-C symmetric stretching bands. Principal factor analysis applied to the set of CxO stretching bands revealed two indepe

## Abstract The Raman spectra of human IgG, IgM, and rabbit IgG in lyophilized form and solution are reported. The spectral results indicate that the predominant structure in these immunoglobulin proteins is the antiparallel β‐sheet. The Raman spectra have also been obtained of rabbit anti‐ovalbumi
