....the oxygen and the two hydrogen atoms as locations of electrostatic charge, with coulombic interaction VC as in table 1. Alternatively, four site models such as TIP4P [62] move the charge from the oxygen towards the hydrogens along the bisector of the H O H angle. Five site models such as ST2 [64] and TIP5P [65] have charges on the oxygen, the two hydrogens, plus two isolated sites located so that the hydrogens and the 2 additional charge sites form a regular tetrahedron centered around the oxygen atom. The various models mentioned here are illustrated in Fig. 3 and compared in [62,65] ....

....of eq. 2.3 1] 3 is about 0.005 t or 10 fs. In order to simulate practical molecules, the determination of the potential function is very important. For example, many intermolecular potential functions have been proposed for water. The simple form of classical ST2 potential proposed by Stillinger and Rahman (1974) has still an advantage in computer task and in physical simplicity. The CC potential by Carravetta and Clementi (1984) that was constructed by fitting to the ab initio molecular orbital calculations has certainly better accuracy. Recently, SPC E potential by Berendsen et al. 1987) which ....

To simulate the effects of short range forces more accurately, we use a multiple time step algorithm in our BD code. A shorter time step of 2 fs is used in the mouth regions of the channel, where U B is active, and in the narrow regions, where U IW is expected to contribute significantly. A ....
