The Mori formalism, a critical discussion of its use in representing far infrared and microwave absorptions

✦ Synopsis

The three variable Mori formalism for molecular dynamics in the fluld state is evaruated using some extensive data of Gcrschel's on three strongly dipohu symmetric tops in the microwave and far infrared region of the electromagnetic spectrum. It is found that the use of loss and power absorption coefficients can lead to misleading results when theory and expcrimcnt are compared and it is csscntial in general to get the data over the whole frequency range of interest. Using this procedure it is found that the second memcry function of the Mori continued fraction is difficult to approximate satisfactorily with a simple decay (such as an exponential) and it is unlikely that successive mempry functions of the total orientational correlation function are simpler functions of time than the latter.

Committee reports. Report on patent law

Committee reports. Report on patent law revision**The evidence in support of the Preambles and Resolutions and suggested additions to the copyright, patent and trade-mark laws contained in the first part of our report was not published in the May Journal owing to want of space. I am now sending you the remaining part of the report, by request, as it is considered quite necessary for the members of the Association to have in their hands before the next annual meeting, the entire document for consideration and study. It is believed that this will decidedly facilitate matters and save much time at the annual meeting which otherwise might be used up in unnecessary discussion of the subject.Your Committee wishes to again emphasize that fact that we have no desire to impose our personal views on the Association. The copyright and patent laws were designed to promote progress in science and the useful arts and the trade-mark laws to protect the public from fraud and imposition. It is generally conceded that the laws as now interpreted and applied fall short in accomplishing their purpose. It is therefore incumbent upon the A. Ph. A., representing the pharmacists of America, to suggest proper modifications of the law, of such kind as to secure the very important objects for which they were enacted.—F. E. Stewarcth, Chairman.
