Snow Mould

Chemical tests for control of snow mould of turf grass and alfalfa were conducted at Edmonton from 1945 to 1957. Of a number of chemicals tested, inorganic mercury salts provided the best control. Mercuric chloride was more effective than mercurous chloride for treating alfalfa but no difference in control was observed from the two chemicals on turf grass. Sodium tetraborate sprays applied to the foliage of alfalfa in early fall gave remarkable control of the disease but are not recommended because of the low margin of safety from boron injury.

Abstract45Sc NMR chemical shifts, linewidths, and longitudinal relaxation rates have been measured in aqueous solutions of scandium chloride and sulphate as a function of the appropriate acid. A common typical behaviour of these parameters without sudden changes has been observed. Also signals in the basic range have been obtained. H2O -D2O solvent isotope effects on Larmor frequency and relaxation rates are presented.

AbstractThe NMR lines of 109Ag have been investigated in solutions of several silver salts in acetonitrile, propionitrile, pyridine, and ethylenediamine, and also in aqueous solutions of Na2S2O3 and ethyl-amine. In these solvents the Ag+ -ions form one or several complexes. In any case a single NMR line was to be detected, i. e. a rapid chemical exchange between different complexes in a sample may be assumed. The concentration dependence of the chemical shifts was determined with high accuracy for these solutions. From these results the chemical shift data of some defined complexes were derived. The chemical shifts of mixtures of AgCl and AgBr and also of AgCl and Agl dissolved in 70% aqueous solution of ethylamine are linear functions of the anions mole fraction. In two samples of AgNO3 dissolved in organic solvents, the ratio υ(109Ag)/υ(107Ag) = 1.149 640 (1) was measured in good agreement with the value from silver salts in aqueous solutions; i. e. no primary isotopic effect was to be detected within these limits of error (0.9 ppm).

Abstract95Mo Fourier transform nuclear magnetic resonance studies were made on aqueous solutions of oxo thiomolybdates. Chemical shifts up to 2200 ppm were found for the different unambiguously assigned species MoO4-nSn2- (n = 0, 1, 2, 3, 4).
