#2: calculating a complex output exactly and to 10 sig. figs. #3: london"s quantum-mechanical treatment of the interaction between two induced dipoles. Expression for the energy of interactions due to dispersion forces between two identical atoms. Na = avogadro"s number (units: mol^-1) h = planck"s constant (units: js) r = separation (units: m) a = atomic polarizability (units: m^3) u= frequency of oscillation of the dipoles (units: s^-1) Na = 6. 022 * 10^23; h = 6. 626 * 10^-34; r = 5. 0 * 10^-10; a = 0. 396 * 10^-30; u = 5. 21 * 10^15; Na = 6. 022 * 10^23; h = 6. 626 * 10^-34; r = 5. 0 * 10^-10; a = 1. 63 * 10^-30; u = 3. 39 * 10^15; Na = 6. 022 * 10^23; h = 6. 626 * 10^-34; r = 5. 0 * 10^-10; a = 2. 48 * 10^-30; u = 2. 94 * 10^15; N@-h3 * na * h * u *ha^2ll h4 *hr^6lld.
