Across this entire regime, NMR observables can report on the amplitude of atomic motion, and the kinetics of atomic motion can be ascertained with a wide variety of experimental techniques from real-time to milliseconds and several nanoseconds to picoseconds.
The distance between two points in space can be ascertained with a rod, or a tape, or by optical means, and the result depends essentially on the physical behavior of the instruments used.
"While Juniper Research has questioned key players on their expectations of the market for both their own projects and the market as a whole, we believe that only when several commercial rollouts are underway can adoption rates be ascertained with a high degree of certainty".
Skill level can be ascertained with a much shorter selection.
