Zum Verhältnis der Kernquadrupolmomente der beiden Molybdänisotope Mo⁹⁵ und Mo⁹⁷

Abstract

The NMR line widths of the isotopes Mo⁹⁵ and Mo⁹⁷ were measured in liquids, where the relaxation time is determined mainly by electrical interaction. From the ratio of the line widthsδH ₉₇/δH₉₅=83, the ratio of the nuclear quadrupol momentsQ ₉₇/Q ₉₅=9,2 could be derived. The instrumentally limited range of line widths, which could be investigated, was 0,1 to 10 Gauss. The line widths of both isotopes were measured in this whole region in an aqueous solution of K₂MoO₄, the viscosity of which was varied by adding different amounts of cane-sugar. The line width ratio was evaluated by a graphical method.
