Me to nBu）和nBu 4P+离子似乎都使氢键平衡向有利于物种II的方向移动。随着溶液温度的升高，这些结构位移（ATstr）的幅度减小。对于碱金属卤化物，Tgtr显示Li+和F-降低物质I的浓度，而对于其它碱金属和卤化物离子则发现相反的情况。这些离子的结构破坏能力的相对顺序为F ~+< Cl~+< Br~+< I ~+和Li ~+< Cs ~+< Na ~+、Rb ~+< K ~+，在10-40 ℃范围内没有明显的温度依赖性。
Me to nBu) and nBu4P+ ions all appear to shift thehydrogen-bonding equilibrium in favor of species II. The magnitude of these structural shifts (ATstr) decreases as the solution temperature is increased. With alkali halides, the Tgtr show that Li+ and F" decrease the concentration of species I, while the opposite is found for the other alkali metal and halide ions. The relative order for the structure-breaking abilities of these ions is F"< Cl~< Br~< I" and Li+< Cs+< Na+^ Rb+< K+, with no noticeable temperature dependence in the range 10-40.
