Question

Given that the spacing of the lines in the microwave spectrum of 27Al1H is

constant at 12.60 cm1

. Calculate the moment of inertia and bond length of

the molecule.​

Answer 1

1.6576 x 10 ^ -8 cm or 1.6576 Angstrom  .

According to the condition given that the spacing of the lines in the microwave spectrum of 27Al 1H. The moment of inertia and bond length of constant at 12.60 cm-1 the molecule is calculated and the answer would be 1.6576 Angstrom.

The solution is given below in an image.
