The boron flame bands have been observed in absorption during the flash photolysis of mixtures of boron trichloride and oxygen. Detailed analysis of the spectrum has shown that the bands arise from two electronic transitions in the linear symmetric molecule BO 2 , [Formula: see text] and A 2 Π u −X 2 Π g . The main mo…
The complete-matrix least-squares analysis on the neutron diffraction intensities of CaC2, YC2, LaC2, CeC2, TbC2, YbC2, LuC2, and UC2 yielded the C–C distances in the C2 groups, 1.191±0.009, 1.275±0.002, 1.303±0.012, 1.283±0.004, 1.293±0.009, 1.287±0.010, 1.276±0.012, and 1.340±0.007 A, respectively. The statistical a…
sections for electron microscopy has become the accepted practice in recent years. Salts of metals of high atomic weight such as uranium, chromium, thorium, lead, or tungsten, among many tested, have been found suitable (6, 1). "Lead hydroxide," as preparted by Watson (6), is now widely used, hut thi…
