Plane, Robert

In 1944 Wellington bomber R for Robert was on a training mission in Scotland. During the course of the exercise the plane experienced difficulties and was forced to ditch into Loch Ness with the loss of one crewman. The bomber settled on the bottom of the lakebed and lay undisturbed for years. Divers discovered her 10 years ago in a remarkable state of preservation and a decision was taken to raise her from the lake and undertake a complete renovation of the aircraft. Among the items found on board was an Elsan toilet, undamaged and in excellent condition. The problems of maintaining and sanitising toilets on wartime aircraft were not key issues at that time, but today this aspect is extremely important in civil aviation.

Robert Plane I would like to comment on the photochemistry of these complexes, particularly the chromium which I think are well chosen for at least two of Dr. Gray s reasons. First, in the case of chromium, unlike cobalt, the charge transfer band is well separated, so that one can study the d-d transitions, at least in certain systems where one has six ligands all alike, and there is no Jahn-Teller splitting, and one has a fairly good idea as to the assignment of bands. 

Roberts et al. (523) emphasized that the in-line mechanism almost requires that two different groups deprotonate the 2 0H and protonate 05 since they are on opposite sides of the basal plane. They are physically removed from each other with a negative P-0- between them to trap any shuttle. Since they observed 3 -CMP interactions with His 12 and 119 by NMR with the greater effect on His 119 and both histidines protonated and since the X-ray structure shows the phosphate between the two histidines, they believed that both histidines are directly involved. Furthermore, the interaction of His 119 is more sensitive to the specific... 

In another method, Roberts and Tabor201 measured the electric double layer repulsion between a transparent rubber sphere and a plane glass surface separated by surfactant solution. As the surfaces were brought together, the double-layer interaction caused a distortion of the rubber surface which was monitored interferometrically.

The existence of these different practices was not sufficient to create a discipline or subdiscipline of physical chemistry, but it showed the way. One definition of physical chemistry is that it is the application of the techniques and theories of physics to the study of chemical reactions, and the study of the interrelations of chemical and physical properties. That would mean that Faraday was a physical chemist when engaged in electrolytic researches. Other chemists devised other essentially physical instruments and applied them to chemical subjects. Robert Bunsen (1811—99) is best known today for the gas burner that bears his name, the Bunsen burner, a standard laboratory instrument. He also devised improved electrical batteries that enabled him to isolate new metals and to add to the list of elements. Bunsen and the physicist Gustav Kirchhoff (1824—87) invented a spectroscope to examine the colors of flames (see Chapter 13). They used it in chemical analysis, to detect minute quantities of elements. With it they discovered the metal cesium by the characteristic two blue lines in its spectrum and rubidium by its two red lines. We have seen how Van t Hoff and Le Bel used optical activity, the rotation of the plane of polarized light (detected by using a polarimeter) to identify optical or stereoisomers. Clearly there was a connection between physical and chemical properties. 

Properties of the Peptide Bond In x-ray studies of crystalline peptides, Linus Pauling and Robert Corey found that the C—N bond in the peptide link is intermediate in length (1.32 A) between a typical C—N single bond (1.49 A) and a C=N double bond (1.27 A). They also found that the peptide bond is planar (all four atoms attached to the C—N group are located in the same plane) and that the two a-carbon atoms attached to the C—N are always trans to each other (on opposite sides of the peptide bond).
