More than 10 years have passed since the memorable symposium on "Myocardial Contractility," edited by R. D. Tanz, F. Kavaler and J. Roberts (New York and London, Academic Press, 1967). PathogeneSis of myocardial failure still involves many questions. The latest scien tific findings on fundamentals of myocardial contraction encouraged us to organize this international symposium held in Rottach-Egern at Tegernsee (Germany), June 17 to 19, 1976 sponsored by the European Society of Cardio ogy. It seemed appropriate to assemble prominent workers in this field in an attempt to correlate their...

The Raman effect is a most useful tool for the study of molecular vibrations and molecular structure. Information about the structure and symmetry of molecules, as well as about their vibrational energies can be obtained to a reasonable degree of satisfaction from their infrared and Raman vibrational spectra. The body of knowl- edqe of the vibrational infrared and Raman spectra of molecules is immense and is now so well organized and understood that it is found to be represented in any stan- dard upper level undergraduate curriculum in chemistry. The rotational energies of a molecule and...
