which system does not have a zero point energy? a. particle in one dimensional box (b). one dimensional harmonic oscillator. (c) two particle rigid rotor d) hydrogen atom
Result : (c) Two particle rigid rotor
We know that , the lowest possible kinetic energy is known as zero point energy. Or we can say the lowest energy level having the energy "zero point energy". Particle in one dimensional box , one dimensional harmonic oscillator and hydrogen atom have zero point energy. They have ground state energy.
But for a rigid rotor, we force it to be at a node initially , it means its zero point energy is 0. It does not have initial energy.
