Molecular modelling -  the  computer  simulation  of molecular structure, properties, and reactivity -  is an invaluable tool for the design of new chemicals,gases, pharmaceuticals, and  materials. Molecular modelling 
can also provide powerful insights into  most  reaction mechanisms. Yet it is often difficult  to tell  where  the inherent value of computational  chemistry  ends  and turns into the hype and hoopla  surrounding  any  new exciting technology.  
   You  can  get   the   answers   you  need  without  an enormous  investment in hardware, software, and  pro personnel costs.  And you'll get straight answers from theochemist   with  over  37  years  of  experience   at designing  and  running  computational  experiments - experiments that  take  a  practical  approach  to  real questions about (bio)chemical systems & reactions.
