For ortho-hydrogen, the nuclear wavefunction and the rotational quantum number, respectively, are

(a)antisymmetric and even

(b)symmetric and odd

(c)symmetric and even

(d)antisymmetric and odd

Answer

Answer: B ✓ checked by 4AB · confidence high

Explanation

Ortho-H₂: symmetric (triplet) nuclear spin function, so the rotational function must be antisymmetric — odd J (b).
