Abstract.
X-Ray Magnetic Circular Dichroism experiments have been conducted on a vanadium inorganic salt and a vanadium enamino-ketone complex. Measurements at the K edge of oxygen and nitrogen reveal the amount of magnetic moment transferred in the 2p orbitals of the ligand atoms from the magnetic V ion. Measurements at the L edge of vanadium show that the orbital moment is small and that J = L + S, contrary to the expected J = L-S coupling for a 3d metal with less than five d-electrons. This surprising inobservance of Hund’s third rule emphasizes the need for more detailed studies and calculations on such hybrid molecules.

Despite many attempts we did not succeed in measuring the in-plane and out-of-plane susceptibilities of the Langmuir-Blodgett sample. Because of the minute amount of material on the slide, the signal was very weak, and diamagnetic corrections unrealistically large
The energy states can be further split (superhyperfine coupling) by neighbouring atoms such as 14N

This agreement with the expected atomic value, S z =−0.5 \(\mu_{B}\), means that the non-saturated S z value observed for the VO2+ complex could be due to antiferromagnetic interactions
