Vibrations of diatomic molecules are usually modelled by a harmonic potent ial. If the potential is given by x, the correct statement is (a) force is 2x and force constant is 2 (b) force is -2x and force constant is 2 (c) force is 2x and force constant is -1 (d) force is -2x and force constant is -I Thos0 to 1 vibration rotation snectrum of a diatomic molcule exhibits transitions for R(0),
