Units

FGH1D Uses


          lengths in Ångströms (Å); 1 Å = 10-10 m
          energies in wavenumbers (cm-1); 1 cm-1 = 0.011962 kJ/mol
          masses in atomic mass units (amu); 1 amu = 1.6611 10-27 kg

For torsional potentials instead of lengths, the angle is used in radians and instead of mass the moment of inertia is used in amu Å2.
