| Comment: |
raw data from [BD68a]; PZC=PZNPC; PZNPC is calculated in [LMB95] (PZC=1/2(pK1+pK2) for infinite dilution; SSA from original reference; cited in [CM94], [S84a], [LMB95]; SSD from [Y75] (tritium exchange and geometrical calculation; there 12.2 for geometrical calculation and 12.5 for tritium exchange) |
