The Zeeman effect was observed for two rotational transitions in PH2D and two rotational transitions in PHD2. The combined results were analyzed to determine the ratio of g-value to rotational constant parallel and perpendicular to the symmetry axis in PH3. The results are g∥/G∥ = - (0.0279 ± 0.0015) × × 10-11 sec and g⊥/G⊥ = (0.0128 ± 0.0012) × 10-1 sec. The magnetic susceptibility anisotropy was determined to be χ∥-χ⊥ = - (2.7 ± 0.8) × 10-6 erg/G2 mole. The molecular quadrupole moment is Q″ = = - (2.1 ± 1.0) × 10-26 esu cm2. The diagonal elements of the diamagnetic, paramagnetic and total susceptibility tensors and the second moments of the electronic charge distribution are given and compared to NH3.
