Chemical shift assignments are made for the carbon atoms of the uracil-bisulfite adduct by use of specific labeling with deuterium and carbon-13. The signals of the analogous adducts from 5-chlorouracil and the pharmacologically important 5-fluorouracil are assigned. 相似文献

A simple apparatus to measure the absolute thermoelectric power of solids in the temperature range 4·2–300K is described.
The cryostat and the associated instrumentation is simple to operate. Representative data of measurements on metallic wire
and pressed pellets are given. An accuracy of better than 10% in absolute thermopower can be obtained in this apparatus. 相似文献
