RNA Statistical Potential with psudoatoms

GB EMP based model

GBEMP

  • move multipoles to offisite using movepole.f in ~pren/tinker/tinker-bat/

dipeptide conformational energy

multipole units:
tinker analyze (em option) output debye and buckinghams for molecular momonets. same as gaussian /g03 
readcrsdict.f of our coarse code convert deby, buckinghams to e-ang to use in tinker
tinker atomic multipoles in key file or from analyze (ep) are in electron-bohr and e-bohr**2, they were converted
to e-ang in kmpole.f

quadrupole devision by 3 is because the formulae we have for interaction energy (by Smith ) is for non-traceless Q. 
By dividing traceless Q by 3 we can then use the formulae.
