Parahydrogen and ortho hydrogen

WebOct 17, 2024 · Closed 2 years ago. It is known that Para-Hydrogen has opposite spin and Ortho-Hydrogen has same spin. Therefore, the energy of Para-Hydrogen is lower than that of Ortho-Hydrogen. Therefore, the stability order should be: Para-Hydrogen > Ortho-Hydrogen. Is this true or is the stability order the opposite of what I predicted?. WebFor both para- and ortho- hydrogens, the two electrons are sitting in the same ground state molecular orbital of the hydrogen molecule, so I dont think there is a difference. The …
