The bond distance for HCl is 1.29 A. At the lowest rotational state the energy is zero.(adsbygoogle = window.adsbygoogle || []).push({});

What is the energy and angular momentum Lz corresponding to the first nonzero rotational state?

I m not sure if I am approaching this problem right.

first I did 1.2 A = 8.3 x 10^7 cm^-1

Then I used this equation for energy because HCl has characteristic of diatomic molecule.

E = (v cm^-1)hc100

is this right?
