…The absolute configuration remained a difficult problem, and for a long time, the relative configuration was commonly used, but in 1951, J. M. Jijvoet et al. determined the absolute configuration by anomalous X-ray scattering of sodium rubidium tartrate, putting an end to the problem. Among other stereoisomers pointed out by van't Hoff, the optical isomerism of allene was proved by William Hobson Mills (1873-1959) et al. around 1935. Stereoisomerism resulting from restricted rotation around a single bond (atropisomerism), which van't Hoff could not have predicted, was discovered by Kenner et al. in the early 1920s. … *Some of the terminology explanations that mention "Mills, WH" are listed below.

…絶対配置が困難な問題として残り,長い間相対立体配置が慣用的に用いられたが,1951年ベイベートJ.M.Bijvoetらが酒石酸ルビジウムナトリウムのX線異常散乱によって絶対配置を決定し,この問題にきりをつけた。ファント・ホフによって指摘された他の立体異性のうちアレンの光学異性の証明は,1935年ころミルズWilliam Hobson Mills(1873‐1959)らによって証明された。ファント・ホフが予想できなかった単結合のまわりの束縛回転の結果生じる立体異性(アトロプ異性)は,1920年代の初めにケナーらによって見いだされた。… ※「Mills,W.H.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
