3 . The microwave spectrum of' HF wields lines at the positions { = 22 mm-' (^ + 1 ) where _ _ 0. 1. ?

This is a physical chemistry problem! Please help anyway you can.

3 . The microwave spectrum of' HF wields lines at the positions{ = 22 mm-' (^ + 1 )where _ _ 0. 1. ? .... Evaluate the bond length of HIF .(Hint : The reduced mass of' a heteronuclear diatomic molecule " AB " is : ` =M, + MeNote that if A = B the reduced mass is just MA / 2 . )
