Nuclear Interactions in Deuterium Fluoride

The deuteron and fluorine magnetic resonance spectra in the molecule DF have been studied using the molecular beam method. The observed resonance patterns have been compared with those calculated on a UNIVAC computer. The parameters of the calculation were adjusted until the theoretical and the experimental curves matched. In this manner the spin-rotational interaction constant of fluorine in DF was assigned the value $\left|c_{\mathrm{F}}\right|=160\mathrm{}\pm 1$ kc/sec and the quadrupole coupling constant of the deuteron in DF was assigned the value $\left|d_2\right|=34\mathrm{}\pm 4$ kc/sec, which corresponds to $\left|\frac{\mathrm{eqQ}}{h}\right|=340\mathrm{}\pm 40$ kc/sec.
