- TraPPE: Transferable Potentials for Phase Equilibria Force Field
TraPPE-Coarse Grain reduces the number of interaction sites by merging neighboring atoms into one large pseudoatom segment and extends the range of applicability to large systems TraPPE-zeolite is an accurate force field for all-silica zeolites
- TraPPE: Transferable Potentials for Phase Equilibria Force Field
The development of the TraPPE force field began in the mid 1990’s with Ilja Siepmann’s move to the University of Minnesota The initial target was a united-atom model for linear alkanes (TraPPE 1)
- TraPPE Conventions for Dihedral Angles
TraPPE uses two standard conventions for dihedral angles: The first convention (similar to IUPAC) uses the symbol ϕijkl to represent the dihedral angle as illustrated in the figure above Synperiplanar (cis) conformations correspond to ϕijkl = 0∘, while antiperiplanar (trans) conformations correspond to ϕijkl = 180∘
- 2DHSM - trappe. oit. umn. edu
The 2DHSM method, based on the hydrophobic subtraction model (HSM), utilizes virtual two-dimensional chromatograms to aid the selection of column pairs for LC x LC approaches To this extent, the performance for each of 319,225 column pairs is determined by evaluating 100 virtual chromatograms computed each for 1,000 diverse analytes using four different sets of chromatographic operating
