Homework Statement
Consider the NaCl molecule, in which the atomic weights of Na and Cl are 23 and 37, respectively. The internuclear separation is 0.236 nm, and the ”spring constant” for vibrations is k = Mred ω^2 = 1 × 10^9 J/m^2 . Calculate the energy difference between adjacent vibrational levels. The value of h-bar is 1.055 × 10^−34 J · s. Answer in units of eV
Homework Equations
The Attempt at a Solution
I tried using reduced mass where m(red) = 23*37 / (23+37)= 14.18
Then plugged m(red) in the equation k = Mred ω^2 where i solved for ω = 8396
With ω, I used E=hbar * ω to get E = 8.8548E-31 J
= 5.527E-12 eV, which is wrong.
