HYDRONIUM_SHELL

Section to define the formation of a hydronium as a collective variable. Number of oxygens in the 1st shell of the hydronium. Adapted from Equation (3) in Supplementary Info of J. Am. Chem. Soc.,128, 2006, 11318, i.e. omitting the cutoff function and summing only over the oxygens of water. [Edit on GitHub]
