等温滴定量热法（ITC）

看了一篇文献 根据ITC可以确定物质是分子内包结or分子间包结的 To elucidate whether the self-inclusion occurs inter- or intramolecularly, we carried out isothermal titration calorimetry (ITC) dilution experiments in which we measured the heat change when a concentrated solution of 4 was injected into a calorimeter cell initially containing water.The heat arises from dimers or oligomers present in the higher concentration solution that dissociate upon dilution.[24] ITC dilution experiments with 4 gave rise to a series of endothermic heat pulses that decreased in a nonlinear fashion as the concentration of 4 increased (see Supporting Information). This calorimetric behavior suggests that 4 is involved in an intermolecular self-association equilibrium. 大概意思就是把物质滴入纯水中 最后作图时非线性的 从而说明该物质是分子间包结的 我的问题是 为什么非线性就是分子间包结 那分子内包结是什么样的 谢谢各位~ |
