Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this work are described in the Introduction. Accomplishments are listed and experimental approaches are described briefly. A summary is given of spectroscopy experiments in CS2 and other materials. Conclusions are: i) there is no evidence in CS2 of an unique shock effect other than that resulting from rapid increase of pressure and temperature which accompanies compression, ii) metastable states, which can be sampled only by rapid compression, are achieved in these experiments, iii) chemical reaction rates can be measured and critical pressures and temperatures can be determined from spectral measurements in this regime, iv) changes in the UV and visible spectra of liquids studied vary from no observable effect to shifts of thousands of angstroms in absorption band edges for pressure less than 130 kbars, v) observed spectral changes in liquid CS2 are cooperative in nature and become very small or zero at infinite dilution, vi) a combination of static high pressure and shock compression measurements is particularly valuable in unravelling the physical processes, involved, vii) shock experiments appear to represent a particularly useful adjunct to and extension of chemical processes in liquids under conditions of high temperatures and pressures.
