本文用C-13 INEPT扩散有序NMR谱（DOSY）研究了LDA-THF二聚体络合物的聚集态。在扩散维度中清楚地识别出六种组分，其DOSY生成的13 C INEPT光谱切片与其各自的INEPT光谱非常一致。线性最小二乘拟合所有组分参考点的log D和log FW之间的相关性非常高：（r = 0.9985）。
C-13 INEPT Diffusion-ordered NMR spectroscopy (DOSY) with an internal reference system was developed to study the aggregation state of THF-solvated LDA dimeric complex. Six components are clearly identified in the diffusion dimension, and their DOSY-generated 13C INEPT spectrum slices agree extremely well with their respective INEPT spectra. The correlation between log D and log FW of the linear least squares fit to reference points of all components is exceptionally high: (r = 0.9985).
