11. Only ferromagnetic, antiferromagnetic, and diamagnetic materials can satisfy this condition. 12. Generally, diamagnetic metals promote ISC and have a long triplet lifetime. 13. Most species which can be observed in the gaseous state are diamagnetic . 14. The singlet state has S = 0 and is diamagnetic . 15. It is a colourless diamagnetic solid that is somewhat stable in air. 16. While gold is weakly diamagnetic , tungsten is weakly paramagnetic. 17. The tetrahedral complexes are paramagnetic, whereas the square planar complexes are diamagnetic . 18. Diamagnetic plasma can generate its own internal magnetic field.19. If the materials are not hard, diamagnetic materials ) permit stable configurations. 20. Techniques using diamagnetic materials are relatively undeveloped and strongly depend on material characteristics.
