dipole : positive/negitive contribution to energy dependings on allignment of molecules: negative clusters together will raise molecule. two dipoles in same direction is destabilising
VdWs: strictly = positive interactions that dont include dipoles, random distribution of electrons, takes into account sterics: interaction of where the atoms are; 1,4 for example, two axial hydrogens.
torsion: deviation from ideal angle. rahter than sterics, energy calculated is angle dependent. coz programme is parametised it knows wat the angle should be and tries to optimises it to that.
bend: deviation from ideal bond angle
stetch: deviation from ideal bond stretch
