Question
A gas-phase 127 12 molecule, with a bond length of 267 pm,
rotates in three-dimensional space. The isotopic mass of 127I
atom is 126.905 amu.
ose the zero point energy associated with this fot
-22
The zero point energy is 2.59 x 10 J.
The zero point energy is 1.29 x 10-22 J.
The zero point energy is 5.18 x 10-22 J.
There is no zero point energy because the rotation is not constrained.
