The diamagnetic susceptibilities of salts forming ions with inert gas configurations - Part I—The halides of sodium and potassium

Abstract

Although the subject of diamagnetic susceptibility has attracted the attention of many experimental and theoretical investigators during the past decade, it is remarkable that no complete systematic investigation of the susceptibilities of salts forming ions with inert gas configurations has been made. As a result, in comparing experimental and theoretical work, results for various salts obtained by quite different methods are used in conjunction with one another, and it is hardly surprising that the agreement should be of an approximate quantitative nature only in view of the wide discordance of the experimental results. The work of Ikenmeyer is the most complete investigation, but here the susceptibilities of certain salts, notably the fluorides, have not been measured. This is a serious omission for the data upon fluorides should prove to be amongst the most interesting. The present investigation is part of an attempt to obtain a series of results under the same experimental conditions and with the same apparatus, in order that the comparative values so obtained may be as accurate as possible.
