1. The Lennard-Jones (LJ) Potential, .17 VI (R) = 4d + d. R is used to approximate weak attractive interactions between atoms that are not covalently bonded, like Arz. VL-J(R) 2.0 1.5 1.0 0.5 R 0 2 4(b) For Arz dimer, the LJ parameters are d = 0.997 kJ/mol and o = 341 pm . Calculate the equilibrium internuclear distance and the vibrational absorption frequency of an Arz dimer under the harmonic approximation. in wavenumbers (cm ). (Hint: A vibrational transition is allowed only if Av = 41.)
