    Raman spectrum of polyethyleneglycol (PEG) in the solid state is measured.Several devices concern-ing the Raman spectrograph are made to avoid difficulties experienced in the measurements.Follow-ing Raman lines are observed: 1480 (m, b), 1280 (m), 1230 (w, b) 1145-1110 (m, b), 1060 (w, b) and 845 cm-1 (m, b).The vibrations of an infinitely extended helical chain of PEG can be treated with the factor group D (4φ/7) which is determined from X-ray diffraction studies.The character table, numbers of normal modes and selection rules are given. Almost all the lines observed can be inferred to be due to the vibration modes of the Ai species.The discussion on the assignments of several Raman lines is tentatively made from the point of view of the factor group analysis.

    An atomic absorption method for determining a small amounts of magnesium in uranium has been studied. About 3g uranium metal is decomposed by 1: 1 hydrochloric acid in platinum dish and dissloved completely by adding hydrogen peroxide. After decomposition of the sample, uranium is removed by extraction with TBP-chlorof orm solution. Aqueous layer is washed with chloroform in order to remove TBP and evaporated to dryness.
    The residue is treated with dilute hydrochloric acid and calcium solution (2mg/ml) which can prevent the interference effects of aluminium and phosphorus, then made up to 10 ml.The sample solution is sprayed into an air-methane flame and the absorption by the latter of the atomic resonance line of magnesium at 285 mμ is measured. By this method, 0.5-15 μg/ml of magnesium in solution can be determined in the presence of aluminium and phosphorus.
