WebbLangevin's theory of diamagnetism and van Vleck's quantum-mechanical theory are reviewed. Ionic susceptibilities, their evaluation by various means from experimental data and their calculation, are discussed, but it is questionable if so much space should have been given to Fajans's theories of deformation of ions.
Webb1 mars 1989 · A diamagnetic “Curie-Weiss law” is found in various organic liquids and their mixtures by using the magnetic birefringence effect in pulsed magnetic fields up to 40 T. An extended Langevin theory of diamagnetism is applied and the Curie-Weiss constant, which reflects the intermolecular interaction, is determined for many liquids … Webb* 특정용어를 검색하실 경우 익스플로러 메뉴에서 "편집>이 페이지에서 찾기" 메뉴를 클릭하신 후 찾고자 하는 용어를 입력하시면 됩니다
