Compute the translational, rotational, vibrational (compute excluding and including the zero point energy term), as well as electronic (compute taking the zero of energy to be that of the ground state molecule as well as that of the separated atoms) contributions to the internal energy (U) for gaseous ammonia at 25 ºC as well as 1 bar such that the volume is that appropriate for 1 mole of molecules. The mass is 17.024 amu. The rotational constants are 9.44, 6.2 as well as 6.2 cm-1. The vibrational constants and degeneracies are 3336 (1), 932 (1), 3443 (2), and 1616 (2) cm-1. The ground electronic state has a degeneracy of 1 the state is 1A1 as well as the atomization energy is D0 = 1158 kJ/mol.
