Figure 12
The comparison of global-scale and local-scale PRDFs for (a) TMAO and (b) urea. Subfigures (a1 to a2) are results from global-scale and local-scale PRDFs of TMAO systems, respectively. Subfigures (b1 to b2) are results from global-scale and local-scale PRDFs of urea systems, respectively. The PRDF of N-O is examined in the case of TMAO and C-O for the urea osmolyte. It can be seen that, the first peak value of the TMAO PRDFs increases with the concentration, while the first peak value of urea PRDFs decreases with the concentration.
