Salicylic Acids

Infrared spectra of benzoic, o-chlorobenzoic, and salicylic acids in the range 700 to 3800 cm−1 have been studied. Measurements have been made on the three acids in carbon tetrachloride and benzene solutions, at a number of concentrations in each case. The results are interpreted in terms of the molecular species present in each solution and the effect of the solvents on these species. Assignments have been made of the observed bands to the various vibrational modes characteristic of the COOH group.

In situ preparation of cell cultures for ultrastructural investigations is a convenient method by which fixation, dehydration and embedment are carried out in the culture petri dish. The in situ method offers the advantage of preserving the native orientation of cell-cell interactions, junctional regions and overlapping configurations. In order to section after embedment, the petri dish is usually separated from the polymerized resin by either differential cryo-contraction or solvation in organic fluids. The remaining resin block must be re-embedded before sectioning. Although removal of the petri dish may not disrupt the native cellular geometry, it does sacrifice what is now recognized as an important characteristic of cell growth: cell-substratum molecular interactions. To preserve the topographic cell-substratum relationship, we developed a simple method of tapered rotary beveling to reduce the petri dish thickness to a dimension suitable for direct thin sectioning.
