Further the change in the ionic character of the C-F bond in fluorobenzenes calculated on the basis of the change in the coupling constants agrees well with that calculated from F 19 chemical shifts. The coupling constant in trifluoroacetic acid has also been measured in various solvents at ...

The long-range spin–spin coupling constant over six bonds between the F nucleus and the C nucleus in the side chain,(C,F), is reported for 4—F—CH—X—R, where X = O, S and R = CH, CHCH, CH(CH)and C(CH)and (C,F) depends on sin θ, where θ is the angle...
The portion of the applied load that is carried by the bolt is dependent on the relative stiffness of the bolt and the clamped parts. This relative stiffness is known as the joint constant, C: The following is a representative diagram of bolt load as a function of the applied joint load:...
Following [45, 46] the coupling constant of a NR superpotential term of the form \begin{aligned} \int d^2\theta \,{\mathbb {X}}_1\cdots {\mathbb {X}}_N \ ,N \ge 3, \, \end{aligned} (5.2) is proportional to the correlation function \begin{aligned} \langle {\Psi _1 \...
