MC-QM analysis

FIGURE 1.5 Multiscale modeling in computational pharmaceutical solid-state chemistry. Here DEM and FEM are discrete and finite element methods MC, Monte Carlo simulation MD, molecular dynamics MM, molecular mechanics QM, quantum mechanics, respectively statistical approaches include knowledge-based models based on database analysis (e.g., Cambridge Structure Database [32]) and quantitative structure property relationships (e.g., group contributions models [33a]). 

The analysis of the properties of mesityl oxide in aqueous solution was based on the continuous and discrete models of the solvent. Here, we used the polarizable continuum model (PCM) [32, 33], and for the discrete model of the solvent, we performed the sequential use of quantum mechanics and molecular mechanics methods, S-QM/MM [20, 21]. In the S-QM/MM procedure, initially the liquid-phase configurations are sampled from molecular simulations, and after statistical analysis, only configurations with less than 10 % of statistical correlation are selected and submitted to quantum mechanical calculations. In our study, we used the Monte Carlo method (MC) with...
