Theory And Experiment

Chiroptical properties of (S)-(-)-1-methyl-2-phenylpiperidine and (S)-(-)-1-methyl-2-(2-tolyl)piperidine have been studied. The preferred conformations have been calculated in gradient way on the basis of the CNDO/2 method, and the rotational forces have been calculated for them by direct procedure using the CNDO/S-CI wave function. For comparison of theory and experiment, molar fractions of the individual conformers have been calculated and used together with the rotational forces for construction of the CD spectrum which has been compared with the experimental CD spectrum. Absolute configurations of the mentioned compounds have been determined by chemical correlation.

I became involved in electron optics in early 1945, when my husband Robert and I were hired by the Farrand Optical Company. My husband had a mathematics Ph.D.; my degree was in physics. My main responsibilities were connected with the development of an electrostatic electron microscope. Fortunately, my thesis research on thermionic and field emission, in the late 1930s under the direction of Professor Joseph E. Henderson at the University of Washington, provided a foundation for dealing with electron beams, high vacuum, and high voltage.At the Farrand Company my co-workers and I used an electron-optical bench to carry out an extensive series of tests on three-electrode electrostatic lenses, as a function of geometrical and voltage parameters. Our studies enabled us to select optimum designs for the lenses in the electron microscope. We early on discovered that, in general, electron lenses are not “thin” lenses, and that aberrations of focal point and aberrations of focal length are not the same. I found electron optics to be an intriguing blend of theory and experiment. A laboratory version of the electron microscope was built and tested, and a report was given at the December 1947 EMSA meeting. The micrograph in fig. 1 is one of several which were presented at the meeting. This micrograph also appeared on the cover of the January 1949 issue of Journal of Applied Physics. These were exciting times in electron microscopy; it seemed that almost everything that happened was new. Our opportunities to publish were limited to patents because Mr. Farrand envisaged a commercial instrument. Regrettably, a commercial version of our laboratory microscope was not produced.
