The first experimental observation of He2 was reported in 1993 [J. Chem. Phys. 98, 3564 (1993)]. Assuming the well depth is only 8 cm (from dissociation energy measurements) and has essentially a harmonic oscillator form up to the dissociation energy, calculate an upper limit to the force constant k for this intermolecular potential energy curve. Express your answer to one significant figure and include the appropriate units. h = 1.055 · 10-34 Js 1 amu = 1.661 · 10 HA -23 1 cm = 1.986 · 10 J k = Value Units The first experimental observation of He2 was reported in 1993 [J.
