The columns are labeled according to the number of derivatives of ΔG0 with respect to temperature, the rows according to the urea-concentration derivatives. The value ΔG0 can be conveniently expressed in terms of Tm or c1/2. Parameters, which are insignificant and can therefore be set to zero, have been bracketed. See text for details.
